It never ends. I was working on the car the other night and sparked the postive post on the rear of my 1 wire alternator. Thought nothing of it.

Tonight I go out and window, fan radio all work, but when I went to turn the starter. It 'clicks!" Battery shows 12-14 volts. Connections at starter and battery are all solid and tight.

Jumped the battery and it fired up. Let it run for 20 minutes while timing car and checking for coolant leaks (just put in new Spal fan sensor and coolant).

After 20 minutes, I turned it off. Went to start it a few minutes later and same "clicks" from the starter again. Jumped it and fired right up.

1. Do you think I fried the alternator when I sparked it the other night with a wrench?

2. How can I test the 1 wire alternator to see if it's putting out volts to the battery? Any way to use my hand held volt meter?

3. Or do you think it is my battery that is bad?
