So a few weeks ago I put a new exhaust system on my Tao Tao VIP, It looks and sounds great but it melted my right rear turn signal and that had some very ill effects on the lighting system. I replaced the main fuse in the battery box, the left side controls (horn, turns, hi/lo), all the bulbs, and the main 4 plug voltage reg. Still no turn signals, headlights, running/brake light, tag lights. It starts right up and runs no problem, gas gauge works, tach works, and the amber running light upfront works. What am I missing here? I'd love to be able to safely ride my scoot again and I'm at my wits end trying to solve it.

JR This needs ah movingI take it they promised you that it was a hot exhaust? Guess you thought they only meant look and sound.  Seriously though, while i wouldn't know where to find the problem, i'd approach it by looking for a wiring diagram, there's prolly a generic 50cc one in the tech files section here. From there i would starting testing for voltage and working your way back (towards the main fuse) until you find the problem. Pain in the and time consuming, but its prolly the best bet.

If your wires melted you might have a bunch of wires grounding the lighting system because they are melted to the frame. Your scoot shouldn't get hot enough to melt the wires though, I just went for a 300 mile trip the other day riding all day long and I didn't melt a thing haha. You may also/or have a fried regulator due to the heat and melted wires. Don't forget to check the bulb filaments.
Just because you changed everything doesn't mean it isn;t all fried now too, if you had a wire melted to the frame and it evaded your inspection and is still melted it may still be doing damages.
Check the stator wires as well, they are usually located tied to the frame above the exhaust pipe.

I really wish I could see the damage...... Do you have a camera?
Although it's only a two wire connection to each blinker, if indeed the harness melted you may need to do some pealling/splicing and tracing. Not a fun project.
BTW, Hows the weather in Florida ?

I agree with all. You almost certainly melted some wires together, or to the frame. Find them! Cut off the melted portion, and separate the wires. I bet your lights will work when you do that.

I'm going to try and hunt down the wires this weekend, the weather is hot and humid! Those storms missed us but still dumped allot of water which jumoa the humidity far to high to deal with wiring outside on a sunny day.
I don't disagree that I could have melted some wires but wouldn't my fuse keep blowing?

It could have melted the power wire out of the stator. It could have melted some of the wire harness from the stator, and that wouldn't have blown the fuse. The headlights are before the battery. There are a lot of ways it could have shut your lighting down without blowing the fuse.

Maybe his lights are setup like a christmas tree? I wouldn't be surprised since it is a taotao.

Those storms missed us but still dumped allot of water which jumoa the humidity far to high to deal with wiring outside on a sunny day. I don't disagree that I could have melted some wires but wouldn't my fuse keep blowing? If wires are melting and the fuse is NOT blowing then that could mean the fuse is not the right amperage. It would seem the wires are not able to handle the amperage that the fuse has. The fuse should burn out before the wires. It also could be that when wires that are melting (for whatever cause) that they are also melting adjacent wires. Then that might confuse the original cause for the melting. Sounds like the wiring needs a good thorough check front to back, top to bottom. If you could find a wiring schematic for your particular scooter, you'd have a much easier time of tracking down the problem. A multi-meter would be a good tool to have to help diagnose electrical issues. If you are going to spend money to upgrade your bike, a few bucks more for a tool that can help you out would just seem a smart investment. Harbor Freight has them for cheap. |

If there is a problem with the wiring coming out of the stator, it won't blow the fuse. The fuse is between the battery and the blinkers and taillights. Power from the stator is before the fuse, and will not blow it.
