For the majority of Chinese 150cc GY6 scooters the brake lights are in the same loop as the starter, which will only start with the brake handle pressed -- which in turn completes the 12v DC circuit for the starter. With the key turned on but the engine not running, the only things that will be getting 12VDC power are the brake lights, horn, turn signals, and some of the instrument lights. Once the engine starts, the rest of the system will be energized.

one possibility: it could be a bridge rectifier converting 12v AC to 12v DC. In this case the AC input would be the yellow/green while the DC output would be the brown/black

I think even the Chinese are now seeing eScooters as the natural replacement for the late, great 50cc. Change is inevitable. And it's coming sooner than you think.

Well, the replacement parts are ordered. When I disassemble everything I guess I'll finally figure out why a new, 300mi scooter has such behaviors. Other than this new, unwanted behavior, and the lousy stock carburetor (replaced early on with a NIBBI CVK26), the bike has been pretty decent so far.

So I decided to purchase a 13" GY6 "Roketa style" rear wheel with provision for bolting on a disc rotor in the future if needed (Note: my rear swing arm already has provision for mounting a rear caliper). I also ordered some "racing" drum shoes with slots to reduce the chance of glazing. Lastly I purchased a 140/60-13 Kenda tire (vs. the stock 130/70-12) which should deliver about 3% more top end as it has a bit more diameter than stock. I'm hoping these new drum brakes last for a while for I have other projects that are more pressing. But having near-zero rear brakes is simply a non-starter for me. I'll let you know how it goes.

yikes, those can be expensive! Any "decent/cheap" ones out there that you could/would recommend?

Make sure that the output shaft on your bike is not just ever so slightly tweaked as well. Matt Good advice. Other than using a straightedge and eyeballing, is there a better way to validate the output shaft is not tweaked? M

So I just discovered that my GY6 150cc rear wheel significantly "rubs" against about 33% of the rear drum when I turn it. Obviously, this is bad both for fuel economy as well as the health of the drum itself and the brake shoes. Given that the drum is integral to the wheel on these scooters does this mean I need a new wheel? (I'm highly doubtful that anyone would be willing to machine the drum true and besides, it likely would cost more that a replacement).
Thoughts/experience?

I was searching recently to see if there was anything I could buy to protect the plastic headlight lenses on my recently-acquired Jiajue Zuma 150cc (bugeye) clone. Measuring the diameter of this scooter's headlights came to exactly 5" round, not the 5 3/4" I was expecting. With a little bit of hunting I found that Lamin-x offer "universal" round film protection in a wide variety of sizes and colors. And sure enough, they have 5" clear which is precisely what I was looking for. Here's the link:
Once the package arrives, I'll install and send pix. Cheers M P.S. I could imagine this stuff used to protect all sorts of stuff on our scooters. Note that they offer different films for painted surfaces vs fog lights vs. headlights. Not sure what the difference is.
