I recently installed a new tire-driven bottle style generator on my 70s Samurai, but the tail light just won't work. I fiddled with the wiring, tried a different bulb, took apart the tail lamp assembly, but no luck. I tested the generator with a different tail lamp entirely and it still didn't work. Has anyone here taken apart a bottle generator and gotten it to work properly? Headlamp output works just fine, but the tail lamp doesn't seem to be getting any power.
