Battery is draining when running...generator and regulator work.
Im running into a problem where the battery is draining when running. 73 XLCH
I have the bike set-up as basic as possible. In SC motorcycles arent required to have turn signals, hence the reason there isnt any. Heres my wiring diagram:
J1 and J2 are the little junction relays under the seat
TL = Tail light
Ultima = digital points
Reg = generator/regulator
HL = headlight
The big circle with IG ST and B is the ignition switch. Its a genuine Harley-Davidson 3-position ignition. Those letters are what is on the switch itself.
The box with the 1 2 3 squares is the junction bar behind the headlight.
The ignition switch works great, off (position 1) shuts off the bike and is off as it should be. Position 2 supplies voltage and the bike will run in that position with no lights on. Position 3 will run with lights on.
The problem is when the bike is in position 3 it drains the battery when running (lights on). I can watch the voltage drop .1-.2 volts just about every second. If I rev the engine or have it sitting at higher RPMs, it drains the battery about twice as fast. However, if in position 2, the voltage will stay relatively constant and fluctuate roughly .3-.5 volts whether Inrev the engine or not...it fluctuates with a wider swing when holding RPMs but it stays reletively constant.. As soon as I turn the bike off with the voltmeter still attached, I see that the voltage starts going back up about .2-.4 volts each second then tapers off after a few seconds.
The circuit is super simple and all of the wires are individually ran wires as I was having trouble finding a wire harness and connectors, so I just ran the individual wires myself. Nothing sticks out as to why the battery would be draining when in position 3....but maybe Im overlooking something simple? With the voltage staying reletively constant in position 2, that means the generator/regulator is indeed working...right?
