I know many of you guys are much smarter than myself when it comes to electrical, so figured I would run this by you. Haven't dug into it yet, just thought I would get some thoughts beforehand.
Harness is original, but in good shape. Hasn't been cut up, car stored indoors since the early 80's. The only part of the harness that I remember having to repair was the brown tach wire at the coil. New ACD battery, cables, "correct" repo starter w/ solenoid through Ricks. Everything electrical on the car works fine, no charging/drain/ground issues apparent. All the connections at the solenoid are tight.
Issue is: when you turn the key, sometimes it cranks just fine, sometimes it just clicks. And that in sequence, one time it will crank, 1 second later it will click. Sometimes it will crank a few times in a row, sometimes it clicks a few times in a row, only to crank the next turn of the key. Completely random, no apparent rhyme or reason. The battery and charging system are fine, and temperature has zero effect.
I'm thinking its something with the solenoid, even though its all new. I dont see how it would be a "lack of juice" problem considering heat does not affect the symptom and it will be perfectly fine just one second later.
Appreciate any thoughts and suggestions
