My C-124 quit on me the other day, fortunately less than a mile from work. Basically, I have power from the batteries (i.e. lights work), but the motor does not engage. I half suspect the throttle, since it's been a bit flaky over the past few months, but I was wondering what might be the best way to diagnose this problem. I have a volt meter but am unsure which wires to test. Anyone have any tips for this issue?
