The trouble started a month ago when I washed the TO-20. (I posted another thread on that.) I thought I had narrowed it down to the gearshift start switch, so I replaced it a few weeks ago, and it worked fine for a while.
Today, it wouldn't crank again.
FYI: It's a 12-volt conversion, with a one-wire alternator.
1. I have voltage to the "hot" side of the switch, BUT: when I operate the shift lever, voltage on the hot side of the switch drops to zero, which didn't seem right. (The starter does not crank.)
2. When I move the shift lever to the start position, I'm not getting voltage through the switch, to the "starter" side of the switch. The starter doesn't crank.
3. I can unhook the battery cable (at the battery) and I get continuity through the switch, when I operate the switch lever.
4.The switch terminals are not shorted to ground.
5. When it doesn't crank, I think I can hear a small arc/pop, but only the first time I hit the start lever.
What's going on? I admit, automotive electric systems are not my thing. Thanks.
