New member w/ APC chopper electrical questions
Hi everybody, Paddy from NC here. I have an APC mini chopper that has very clearly been around the block with previous owners and backyard ‘mechanics’. I’ll start by introducing that I do have quite a bit of mechanical experience, but in several fields that are NOT mini bikes. That being said, I’m becoming frustrated with this mini chopper’s electrical system. It’s also worth a mention that there are several cut and splice segments that are clearly not factory.
The headlight, taillight, and gauge lights seem to be in normal working order. The turn signals have all been smashed or chopped right off. The turn signal relay does let out a terrible screech when i activate the switch in either direction, but I’m not too concerned with that right now.
My major concern is the electric starting circuit. I’m able to crank the engine by manually closing the output lugs of the starter relay under the gas tank, but the starter switch next to the throttle does not activate my solenoid. I’ve gone through the switch, relay, and the circuit between the two with an ohmmeter and have no reason to believe that either is faulty. I could be wrong and dealing with a faulty input side of the relay, which seems most plausible. I’m honestly not quite sure how to explain it any further and I’m hoping someone has dealt with similar issues. I don’t want to start throwing parts at it if
I’m not sure what’s going wrong. One thing I found extremely odd was constant continuity between both input poles of the relay(powered or not, ignition switch both open and closed), but still having normal starter operation when I short the output poles. Could I have a bad relay magnet that’s causing this problem? I’m stumped.
One more quick question that seemed odd to me... a two position key switch but with 4 wires, and 2 more unused poles? This makes no sense to me. Why not a two position key as battery cut-off rather than running small-gauge wire all over the place?
Sorry for the long post guys, I want to try to be thorough with my description! Thank you so much for any insight you can provide!!
