What a turd that thing is. *sigh*

A friend with a sprint came over last night, to have me install the scooterworks electronic ignition kit on their bike. I already had my trepidations, because scooterworks is still selling a very old-style bajaj setup.

1) No instructions. Not even something to say "orient the hall sensor at 12 o'clock" or whatever. Weak. I'm lucky i've seen pics of these installed before or i would have had no idea how to hook this bloody thing up

2) Missing all the screws / nuts / bolts you need to hook the CDI and coil to the bracket. Once again, something that could have been included easily.

3) it's 6 volt ?!?!? wtf? Who makes a 6 volt electronic ignition kit these days? I thought they were all just 12v standard ?

4) Plastic flywheel fan? Not just shitty plastic, but molded WAY TOO BIG. We had to grind it down on the concrete just to make it fit, and even then the fins rubbed on the inside of the flywheel shroud and made a horrible screeching sound. Going to take even more grinding to make it work properly. Absolutely the shittiest part of the system

5) claims that it's meant to work perfectly with their EIK harness ( which we had in the bike already )...but the wire colors don't match up. the power output on the stator is GREEN, the harness uses BLUE as it's main power. I had to bodge on a kill switch wire because i couldn't figure out which of the 5 tabs on the CDI were for the kill.

Save your money. [redacted].com is selling one that's a newer style one ..12v, metal flywheel, proper ducati-style CDI and not this ridiculous 2-piece one. I'm ashamed i even put this one his bike. I should have just told him to send it back.

Eric,

I'm having the SAME issues...I followed their "wiring diagram" to a T and I don't have a headlight working at the moment.

I emailed their tech guy 2 months ago and still no response

A "turd" is an understatement...more like a "big pile of shit"

I'm also still confused..6v pr 12v??!!!

Please tell me how you got the headlight to work!!!!!!!!

well... when you bought their wiring harness ( which i think has GREAT quality, ironically )... did you buy their ignition switch and brakelight switch ? ( the brakelight switch could be ANY non-battery ) not sure if you need their handlebar switch, though. I'm sure a regular one could be bodged to work if it didn't work right off.

Was your bike battery before, or non battery ?

The wiring harness was quite nice actually..it was just the "how to make shit work" part of it that was a bit fuzzy.

Yes I got the switch and brake switch to go with it.

I had a 12v battery set up before. I went with the non battery set up (love it).

I also got a AC regulator from Scooters O

So... question:

You're using the Scooterworks EIK kit like i discribed above? AND the harness? Did your realize that thing about the green output on the stator connects to the blue wire on the harness?

Did you also notice that the blue wire is forked...where one part runs to the regulator and the other part runs up to the headlight?

( that's a weird setup. Usually i see the regulator used in a serial configuration ..where it sits inline. The Scooterworks setup uses it in parallel. I have trouble visualizing how that works ) I suppose you could easily convert it, though... just clip the blue wire, remove the pigtail that runs over to the glovebox / regulator, and make ALL the juice run to there, through the regulator, and then up to the headset.

Mate, I wish i posted about this.....too late i guess.

Is indeed crap.

My friend doug buy one last year for his Sprint i ended up removing it after i found a NOS stator etc on Ebay UK. The plastic flywheel is a great frizzbie though.



Cheers

I bought just the wiring harness to hook up the 05 PX motor:

http://www.scooterworks.com/Harness_Kit_Wiring_Conversion_P3721.cfm

It should be the same exact thing your friend bought for his Sprint.

According to their wiring diagram: http://www.scooterworks.com/images/pdf/eik_harness.pdf the violet and brown wire then the ground black from the engine to power the headlight??

I'm confused as hell at the moment. hahaha

time out.


So, you obviously realize the GREEN wire off the bajaj stator is the wire that connects to your BLUE wire on the harness ( which the wiring diagram shows as incorrect ... that the GREEN wire is your kill switch per the diagram, which is wrong if you use the scooterworks bajaj ignition kit ), that takes the juice up to the headset switch. The juice then flows out of the switch over the BROWN and VIOLET wires to the headlight.. ( high and low beam wires ). The headlight also gets hooked up to a black wire up there as well.

But, are you sure you're getting any voltage at all up there? Have you hooked up a multimeter? Your engine runs, i take it ?

hahha..why are you calling it Bajaj? I have a 05 PX 150 motor

OK.

So on my scoot..the green wire (kill switch wire) from the kit hooks up to the last slot on the CDI straight to the switch on the handlebar which is labled "M"...just like it shows on scooterworks wiring diagram.

The green wire from my stator is hooked up directly to the "green" slot on the CDI.

Neither of the "green" wires are hooked up to a blue wire.

Mark (steelcap) tried to help me with his voltmeter...we weren't getting enough juice to the switch to power the headlight.

* chime in Mark at anytime!

My scoot runs like a top!

** Do I need to have the green kill switch wire spliced into the dark blue wire to get power to the switch on the headset?

I've got the ELK harness with scooterworks switches in my Allstate with P motor. Let's know if you want me to take a pic of my set up or something.

Please do!

Eric - how did you get the headlight to work?

Alright, let's rewind.

This bike was a Sprint Veloce, from 1971. It was a weird electrical setup... battery, no turn signals, presumably a key at some point..but not by the point i got to it. It had been bodged to work non battery ( as it had a P200 in it at one point, but had been converted back to the sprint v engine at sale to my friend ), but had really, really weak lights.

I pulled the entire wiring harness out of it, and ran the complete Scooterworks EIK harness. I had a couple little mishaps at first ( one of which was that i left the little wire and plug that runs into the speedo bulb just hanging loose at first, and it was grounding out ALL the juice inside the headset. After i taped it up so it wasn't making contact with the inside of the headset it was fine ( he didn't have a speedo bulb ).

So, i basically bodged his old battery stator by grounding out a few wires, to the complete scooterworks harness.

Besides that, the wiring harness just plain worked. There were no issues, all the switches / lights / horn worked fine.

But he wanted electronic ignition, etc. I said "well, it will be easy to add on, now that i did all the hard work in pulling a new harness".

So last night i put the Bajaj electronic ignition kit on his bike. Once i realized to aim the hall sensor nearly straight up for it to be timed right, it started up just fine. Electrics worked just fine.... after i thought "weird, there's no kill switch wire" and "weird, the green wire is the main power output, and not blue like all their instructions / diagrams say"

So that dark blue wire is suppose to supply the power to the switch on the headset correct?

The dark blue wire on the scooterworks harness? Yes. It's a Y-shaped wire, where the to points of the Y meet at the junction box. One side of the Y goes to the glovebox for you to hook up to a regulator. The other side goes up to the headset to the switch, where all the power is distributed ( to the headlight / taillight circuit, to the brakelight, and to the horn ).

The dark blue matching wire on the Bajaj stator they sell? Trick question! There's not a corresponding wire!

I also ordered one of these things from Scooter Works and noticed that the sticker on the CDI unit did not correspond to what was molded on the plastic. It came with a 150cc motor that I ordered for a friends Vietnam Sprint. I replaced the wireing harness with the EIK and then hooked up the engine and it did not start because I followed the sticker and then figured out that it was mis-labeled. I also installed a new handlebar switch and everything worked fine albeit with a little cussing here and there.

ahhh..don't know why I can't get it to work then

Any way to bodge the wiring to get it to possibly work? I'm open to any ideas

troubleshooting wiring / electrical over the internets is like trying to ride a bicycle with a shopping bag on your head.

If you want to learn how to troubleshoot electrical, all you need is a multimeter with a resistance setting, and a volts AC setting. Resistance will tell you if you have conductivity from point A to point B. You could ...for example... test to make sure your wiring harness is hooked up correcly by insuring there's 0 ohms resistance between the wire at your headlight, and the blue wire that connects to your stator ( when the headlight switch is in the ON position ) for example.

Those are the type of experiments you should be doing. Making sure there's no break in the wire anywhere. If you touch a wire ( for example, the blue one ) and get 0 volts resistance between the frame and the blue wire, then it's grounding to the frame somewhere and that's where your problem is.

Seriously ....embrace the multimeter. Become one with it's lifeforce.

Sounds like you need to swing by and borrow my multimeter Jason

You are 100% correct on that one! Sounds like I'm grounding out somewhere

So, i had the same problem that you're having....

i had the blue wire grounding out somewhere...and was getting no lights.

I unhooked the blue harness wire from the junctionbox, and began testing it...segment by segment... until i isolated where the grounding was taking place.... utilizing the "resistance" method i just cited above... touching one end of the multimeter ( on the OHMS setting ) to one end of the wire, and the other end to the bare frame. As long as there was 0 resistance, there's a ground issue.

And like i said, that stupid speedo bulb pigtail was grounding ALL the juice out inside the headset.

I recommend, before you get too busy with this ... that you just look at that speedo bulb wire i'm talking about, and just put some tape around the bare end of it. Then see if you still have no lights. I seriously spent a good hour or two tracking down that little demon. I had put the speedo bulb wire ( which is still blue, i believe ) into the speedo ..but with no bulb in there. It was shunting all my current to ground through the chassis of the speedo, through the headset, through the frame.

So back to this again.

I think I may go with this wiring harness from ASC:

http://174.36.196.117/index.php?main_page=product_info&cPath=1_29_39&products_id=374&zenid=1189cca7a175873d47892c7b50f4a649

I think I may need this type of switch:

http://174.36.196.117/index.php?main_page=product_info&cPath=1_29_36&products_id=347&zenid=1189cca7a175873d47892c7b50f4a649

Instead of the switch that I currently have:

http://174.36.196.117/index.php?main_page=product_info&cPath=1_29_36&products_id=1193&zenid=1189cca7a175873d47892c7b50f4a649

And if I have the right harness and switch, I could follow this wiring diagram:

http://www.allstyles-scooters.com/12volt_con_wire_PX.htm

Will this work??? Using the Euro (non battery) 12V harness to go with that diagram? I'm just wondering about the switch and which one I should be using.

I went back to scooterworks website and they do not have that wonky wiring diagram up anymore. I feel like I've wasted time and $ using their crap.

I think this company in the UK did a way better job of putting a diagram together with their kit:

http://www.allstyles-scooters.com/P125_loom_vintage.html

my buddy is waiting for a few weeks until [redacted] puts together their complete ducati cdi and metal flywheel conversion kit again. It's out of stock right now.

Really? He sent that junk back?!

different buddy.

that would make him


buddy buddy

Also I was just talking to Mark at Bulletproof and he has started selling wiring harness kits (harness, reg, switches). We were talking about a 12v rally conversion set up, but I'd bet he's making different models.
might want to drop him a line.

But I thought that the SW harness kit was pretty good?

The scooterworks harness is awesome. So is their 6v and 12v 3-pole regulators they sell. ( they are much smaller than the standard ducati style, and i like them a lot )

It's the plastic flywheel i can't stand. I'm not a huge fan of that 2-piece CDI either, with the separate HT coil.

ya plastic fly's seem like a bad idea.
that scooterworks harness, can that be hooked up to an ignition, high/low indicator, etc?

yes.

Hi chaps,

I have the above and am struggling with getting a CDI where the flywheel actually fits the crankshaft - it does not fit on the one I received from SIP

can anyone direct me to the REAL CDI AND wiring loom for a late 64 gs 160 mk2?

help, help , help please

Crombie, You should start a new thread as not too many people are going to check out a 6 year old thread. Good luck.

well - if your using the scooterworks Bajaj style one. Its not made for you scoot.
Get the [redacted] PX style one. Got one for a friends sprint. No issues with install and works perfect.
Get this and be done
