And, the amp meter drops to nothing. It has a new battery, and new alternator. Both have been replaced with with a different battery and alternator, still the same thing. I had to put on a new radiator hose. To do this, I had to remove the alternator. In the process of putting the alternator back on, I dropped it. It did hit (touch) the air conditioning line. I've also replaced the PCM. What else could it be?

Have the alternator tested at the parts store to make sure it was not compromised. By the way, an external voltage regulator can be installed to bypass the PCM, by a qualified technician.

Did this happen before or after the hose replacement and dropping the alt? Was the battery still hooked up at that time?

Before, and yea the battery was hooked up. It did blow a 50 amp fuse in the process as well When all this started happening, I replaced the alternator, battery, and PCM. I also had my old battery and alternator checked, they both checked out ok. I also replaced the fuse.

Check ALL fuses and fuseable links!!! Also check battery voltage, at the cables,, with engine running, should be around 14 volts...Check engine light on? Any codes??

You were exactly right! It was a fuse. Thanks so much for the tip, and saving me money....by not having to take it to the shop.
