First of all, thanks for all the previous help on the engine work. Engine is putting like a dream now.
Now, On to electrical. I currently have the blue wire grounded. Engine fires up fine, and the headlight fires. Without the blue wire grounded, it will not start. So I am assuming it is a tail bulb or a turn signal.
I found a couple of wiring diagrams, however I have not messed with 6 volt AC systems before. So, 2 questions:
1) A burned out tail light will kill the ignition, but will a burned out turn signal?
2) Can i simply ground out all the lights, and then go through and trouble shoot each one one at a time? Or will grounding out the light cause a short that will kill the engine?
