Modern Vespa

Hey bros and broettes!

So over the weekend my dad bought me a vespa for completing probation. Super custom portofino green and brown leather seats. Really low miles 487. So after getting home it wouldn't start. Hooked up the jumper cables to my dad's 2500 Cummins turbo diesel truck. Had two batteries just went with the closer one (right?). Went color to color on the truck and black to red and red to black on the scooter. Made sure to spark before hooking up scooter and then revved the engine quite a bit. It still won't start? Is this junk or should I be looking at the alternator? Possibly bump start it? Would is wrong? Is this a common issue? I'm starting to think vespas suck.

Are you holding a brake lever? Kill switch on Run?

Hope you haven't burned up the voltage regulator by trying to start with the truck.

Still at 14v, so I think the voltage regulator is fine.

So tell us about your scooter. Is it fuel injected or carbureted? If you don't know send pictures of the top of the motor (lift the seat and remove the black plastic tub). With a carb it could have flooded bouncing in the back of the truck. With an injector, you should hear a whining sound start and go out when you turn the key to on.

Do you have a brown and blue set of keys? There's a security system on the scoots that won't let it fire unless you have the right key.

Without the jumper cables does the motor turn over quickly like your car sounds when starting it? Or is the battery so drained it's struggling?

And yea like it was mentioned, is the killswitch set to run and are you squeezing the brake at the same time you push the starter button?

Reverse polarity to jump?

You've blown something on the scooter.

Here's more battery and charger got for free from original owner

Battery still reading 14v

If the scooter battery is reading 14V you don't need a jump.
OTOH, if you blew a fuse, you'll need to replace it.

PS: Vespas don't suck.

That's what I thought until getting this gran Turismo 300!! Where are the fuses????

Here's what was listed about the scooter

5 speed auto clutch? Um.....

But first, and really truly, have you ever had a successful jump start with reversed polarity?

Ported crank is a new one for me, you joshin' with us?

I just want to know why this won't start, I don't like my jump start technique criticized thanks.

Did they make a carbureted 300?

It's entirely possible it won't start because your jump start technique is ...

Say, have you ever seen what happens when you put fine steel wool on a 9V battery?

I guess we'll have to agree to disagree. Never had an issue before.

Uh, what does a drill battery charger have to do with a scooter?

That's the battery charger that came with it for free. Not sure if you've seen this style before it's efficient.

Ah forgot it was a 300 there.

Get that thing started and make a video going 120 MPH!

Folks here are trying to help you. If you truly went black to red, red to black, it isn't a criticism - it is pointing out that you did it wrong.

That was the what the seller wrote. Looked like they really upgraded it, probably why it'll go 120.

Troll banned.
