Need Help Fast! Bypassing The PCM

I think my PCM might be going bad (or I am going crazy). I have found THIS.

Do I hook the regulator to the 2 terminals that are about 1 1/2" apart? does the top go to the top regulator pin and the bottom go to the other pin?


How do I make my A/C function without the PCM?

Yes, the external regulator connects to the two small terminals.

Pull the plug off the AC relay and run a jumper wire between the load terminals in the plug.

I just did this. I took 12 volt keyed power and ran it to the top pin on the regulator and one pin on the alternator. I ran the other pin on the regulator to the remaining pin on the alternator. Nothing.

How can I test to see if my alternator is good?

Is the regulator screwed to something metal? It needs to be grounded to work.

Yes it is. Would it help if I run a ground wire directly to it?
