Modern Vespa

Hi All.

Sorry if this is something that is already out there. Out with the boys last night on a run and on the road back lost my Dip, Main Beam, Tail and Brake Lights. Still have my horn and indicators.

Nothing really noticed before they went, although think i did have a couple of flickers during some higher revs. But other than that worked fine until about 2 minutes from the house (out for a few hours).

Don't know where to start looking...bit of a worrier and initially thought stator/pick-ups...but is there anywhere I can be looking first. Seems strange to lose that lot at once.

It's a P2 running a 210 kit, T Plate Disc Model. Sure I have battery (will double check once home) but the electric start is off.

Any initial thoughts appreciated.

Probably a short circuit or worst... a problem with the voltage regulator. But you should try search for a short circuit, it's the most common.

Thanks PX. Plan to do that this evening. Just throwing it out there to see what suggestions there are. Electrics always been a nightmare as not something I am confident in. See how it pans out. :S

Had a look about this evening and got stranger. Main bulb was blown so thought I was on to an easy fix but alas no...lol. New bulb fitted and when switching between main beam/dip there is a slight orange tinge but nothing you could class as 'light'. Bizarre is I still gave no tail light, however I do have indicators and brake light, only when I have the light switch set to dip...but when I do this I lose the dim orange.

Didn't have a volt meter, so not been able to check volts...not that I am confident in doing this.

Couldn't see any bad earths or shorts....reseated the connectors under the horn cover and checked for corrosion, so lost unless it's the regulator or pick ups on the stator not giving enough voltage.

Must note....all was working fine last night, until I lost the lights on the way home.

The tail light and the indicators run off the battery. I'm guessing you either have a wire grounding out at the dip switch or at the junction of the headset and frame neck. Take a good look at both. You may have to remove the upper headset to get a real good look down there.

Thanks Tierney, will do that tonight...let round 2begin

Had headset off. The switch area looks good, no corrosion or broken wires that would indicate short (good solders). Under the horncover, couldn't see anything that stood out. cleaned up a little corrosion on a few spades, re-seated all the connector block, taped up a couple of wires where the connector had the potential to short but still nothing. So guess I need to look further. Multi meter need so I can ensure the vAC is right. Next step I think.

Well all sorted. Incase anyone is interested it was a multitude of issues...lol. Turned out the rear shock rubber had sheared and cables to rear light had rubbed on wheel, breaking the plastic covers and exposing the the wires...causing the short. Also seemed to lose the CDI unit at some point while fixing as once I found the exposed wires I lost the overall spark. Replaced CDI, fixed shock rubber and taped up the wires....bingo everything wonderful again.

Thanks for all the responses, appreciated.

Glad you got it all sorted. Now go for a ride.
