Diode on 86 corvette ac compressor.
I have been trouble shooting AC problems on my 1986 L98 and noticed a diode on the compressor plug was broken in half. What is this for? Where can I get a new one? Ran all test in FSM and getting 12V to green wire and black wire located at the plug on the compressor. The system is full of freon. Compressor works when I did the jump test. Thanks in advance

This thread help me figure out what was wrong with mine. Sounds like you are missing the ground (signal) wire like I was, you are getting 12 volts to both wires because it's going through the clutch coil and back out... it needs ground to engage the clutch.
