Hey guys,
I'm working on a 1990 Shamrock with a 351 in it and I'm at a loss with the starter. I originally replaced it because it was seized up from not being used for about 4 years. So bought a new Sierra #18-5920 and installed it. The new starter will turn the engine over BUT there was a good bit of electrical looking smoke and a spark coming off a terminal when I cranked it. NOT GOOD. So I started checking all my connections with my power probe and here's the problem, the terminal where my yellow / red tracer wire (Ignition) connects to the starter is reading as a ground. This is with only my main 12V wire connected. If I leave the ignition wire disconnected and turn the key, the wire reads 12v when it receives the signal. So for whatever reason, I've got a 12-volt signal going straight to a ground that should be a circuit that pops the starter. I'm lost.
