Modern Vespa

Electrical is one of the areas I have trouble with so I am looking for help.

After my recent adventure I noticed that the big brown connector under the seat in the front was having a problem, The center "in" wire was melted. Fortunately I had another connector and we replaced it. Stefan knows about electric wires and I let him do the work. Scooter fired up and we measured the temp on all the wires in and out of the plug and they were all the same and normal.

Then I noticed cracks in the headset and Stefan said you got one on the shelf why don't you replace it. Then he left to go surfing on the other side of the state. That headset was on the shelf for a reason. It had been in the "bear wreck" but it looked like the better of the two. It was not. I found this out after I had moved all the switches, now I had to move them all back. This also involved removing the leg shield.

Here is the problem. There is no power to the front light. The one on the horn cover or either light in the headset. There is no power to either one.
I tested all 10 of the fuses and they all test good. I am assuming the horn/light relay is working since the horn works. All other lights work and it runs normally.

So, does anyone have an idea where I should look next to solve the light problem.

So, the lights did work after fixing the brown connector and prior to replacing the headset twice, correct? Do you have power at the hi/lo light switch? I would check there first.

If yes, make sure that the switch is properly wired and is working.

If switch is hot and working, look for a ground that may have been pulled when doing the off/on of the body parts?

If no power at switch - look for others who know this scoot or get the wiring diagram.

Sorry, best I can do…

Thank you.

I believe the lights worked after repairing the connecter but can't swear to it. The connecter is part of the voltage regulator system as I understand it.

Yes the high-low is next on the list as I pull the headset back off.

Thank you Chris was good enough.
It was the high/low switch. The connector was not full in. I had checked to see if it was fully seated and I thought it was. It is in a awkward spot, but once I pulled the switch I found it not fully seated. A little shove and I now have light!!!

The scoter has had a hard but wonderful life. Five round trips across America, four of those Cannonballs and several trips north to Canada and back and lots of miles around the south. It has been a worthy steed and keeps on going

Thank you.

Nice that you could solve the issue.
But reading your message I wonder what mileage you have on your Vespa. Must be huge.

64000. But until last October I had 4 and the two 300's had over 30000. Not as many as many, including my friend WLeuthold, but mine are better miles

Super! Glad to hear you and your well loved scooter are back on the road.
