So I’ve got an electrical question, but here’s some back ground before I ask. I am in the process of making my Coleman street legal. I have added a Horn, Tail light, brake light, front and rear turn signals, and a high beam. My Coleman came with an LED bulb and rectifier from the factory. I added a high beam by installing a high/low beam, LED bulb and running an additional wire for the high beam function. Everything works and looks great.
While wiring the system up, I noticed that none of the electrical would work until I realized that the ground/negative coming out of the rectifier is NOT connected to the chassis. No big deal. I just wired all the negative terminals to the rectifiers negotive lead. Anyways, I had a Chinese 4 wheeler with the same basic rectifier and the rectifiers negative lead WAS grounded to chassis, which must have been done by the previous owner because it didn’t look factory. I had issues with rectifiers going bad on that 4 wheeler and I’m hesitant to ground the negative lead on my bike.
So for the actual question: Does anyone know if they intentionally segregated the negative lead from the chassis? My thought is if they did it intentionally it’s due to noise or voltage back-feed running through the chassis from the ignition system. My other thought is that I’m looking too deep into this, and they just ran the negative lead from the rectifier directly to the headlights negative terminal because it is the cheapest and easiest thing to do.
the reason I’m even thinking about grounding the negative lead from the rectifier to the chassis is because I’m going to install a battery and starter and want to use the bikes electrical system to charge the battery. This can not be done while segregating the negative lead of the rectifier from the chassis without complicating things a lot via relays and or solenoids.
Thanks for any info you have.
