This is definitely heading me in the right direction. I actually had the scooter mechanic (35 years of experience) come to my house and look at it! He said the exact thing. Unfortunately it was too dark for us to begin tracing the wire and find the break. So I'm pretty sure this is the problem. I have to credible sources telling me so So wrong sticker on the engine, how great! haha. This clears up a lot of confusion. Tomorrow after college, I will begin my wiring dance and follow those puppies. I'm so close. I can feel it! Thanks a lot again everybody!

Lol I love this scooter though. When it's running good nothing can stop it, except maybe a going over a very rough railroad crossing and probably knock a critical wire loose (oops, that guy was me). I believe that was the start of all the problems. First my radiator hose came loose and my antifreeze was everywhere. Then that day I put it back on, on a test drive my air filter FELL off of my carborator. Ran it over and bent the clamp. Replaced it and had a lot more pick up after putting it on properly?? Then back tire went flat. Bought a new tire and installed. Fixed that. Then this! I'm hoping this is the end and I can get back on the road Haven't been able to for about a week now. Maybe the scoot just needed lots of TLC. After I get it running back up nice and good I'm going to give it a well deserved wash. Then Joy ride. And again. And again. Thanks a lot guys. If this fixes my problems be looking for donations ;D

Just gotta love this guy's scootin' spirit.

[pop1205]

Lol that actually doesn't sound like a bad idea. May take forever but that's how long I spent trying to figure out what's wrong with my scoot now. haha.

Scootin spirit is the way to put it. I love being in the open and feeling that wind. People just don't understand. Everybody is like why not just get a car, and I look at them and say why not just get a scoot?..

Hopefully tomorrow after tracking down this bad wire I will be up and running like a charm! Wish me luck ;D

Wow Chris - I would excuse you from class to work on your scoot. Good luck and have lots of fun putting all the plastic back together!

[pop1205]

Haha I wish my professor's would! But I'm home now and it's time to solve this mystery! Putting the plastic on is the best part. You get to see it all coming together!

[pop1205]

Well. I haven't found nothing out of the ordinary. I found the wire that my radiator fan linked up with, and my phone, and to my wire bundle for the dimmer switch, blinkers, high beam switch, and horn. Everything is nice and snug. I checked all the ground. The cord that runs everything together is green on mine?? Weird. I also checked the black fuse box by the battery, found it ran to that bundle as well. So I followed and checked it along the way and nothing. This is getting more and more strange. But I will have the scooter mechanic to my house tonight. So hopefully he can see what I can't. Wish me luck!

[pop1205]

Hmmm not sure why I said phone? LOL Phone has nothing to do with this scooter!

Alright. Well I can't find the wire that they all link on. They all link onto this big green wire. I checked all soldered points, everything! Spent 6.5 hours just looking at wires. I don't have an ohm meter or whatever it's called. Maybe I need one now? Everything was connected good!
Tail lights: Usually only one would be on when the engine is on, along with solid headlights and license light. I have non of that now. The only time the head lights come on is when I hit the dimmer switch. And the only time my taillights come on (just the one like it's supposed to) is when I hit the dimmer light plus hit the high beam switch up. If the engine was hot hitting the dimmer switch plus high beam switch up will turn the radiator's fan on. The tail lights work fine when I hit the brakes. Both red lights come on nice and bright.

Any suggestions would be great.
Thanks!

[Cruiser]

Both your taillights should be on. Could be a bad bulb or a problem in the bulb socket. A multimeter is almost a necessity when trying to track down your kind of problem. Harbor Freight has a basic one for around $5. The green wire is a ground wire.

[pop1205]

Both tail lights work. When I hit the breaks they both come on. Just usually when the parking lights are on, there is only one on. It's the usual thing. It was like that since day one. It will be one on in parking light mode and then when I hit the breaks they both come on bright red.

And ok. I have to get one then. Can't tomorrow. I have school 8-10. And work 10-630. Weird. I guess I can teleport to work. Man of miracles!

[Cruiser]

My scoot would not pass inspection in my state with one taillight out. Your one taillight might be the usual, but both are supposed to be on according to the wiring diagram. Does this taillight work with the passing switch? Have you checked to see if the license plate light works? This may or may not be related to your main problem, but it should be fixed. Maybe it's just the bulb. LED upgrades are very popular.

Sounds like you could use a "backup" scoot like my VIP50. If we were scootin' buds I would be happy to loan you my backup.

[pop1205]

Yeah I always wondered about that.
And I'm not sure about plate light. I had my mom check the lights when I was flipping switches and she said she didn't see it on.
How would I go about this? (after of course getting the main problem fixed).
And LED upgrades. Sounds nice, not sure how to do it though. I'm not a very electricity kind of guy. I shy away from messing with electrical things. Which might explain why I'm having such a hard time with my scoot now

And actually I do have a back up! haha a kymco ZX50. But well, I need a back up for a back up. It was messing up. I need to adjust some stuff. Just haven't had the time to get to it.
Thanks for the offer though lol

[pop1205]

Oh, and tail light works when I hit the passer light and flip the high beam switch up. Just the one will come on. If I presses the breaks both come on nice and bright (without the need to hit the passer light switch).

[pop1205]

I have one of my friends from down the street coming over with his multimeter to test each line.
I didn't even know he knew about sccooters! Apparently he took his entire carborator apart, and cleaned it himself. He did electrical problems in his as well!
I will have him test everything to see where the connection stops and see if we need some new wire

[pop1205]

Bought it used from an old friend of the family. He knows nothing mechanical or electrical. But who knows. I will check the diode cables and everything by the regulator to see if it's not connected good or if it's just a bad circuit.

If it is a bad circuit, what would I have to do? Rewire the entire thing? Or what?

Thanks guys!
