87 Chrysler LaBaron charging system

This car is possessed! I have had the alt changed 4 times, the battery changed 6 times, and the ECU changed 2 times. I am still having an overcharging problem. I can drive it, but I have to have my high beams and blower on. The longer I drive it (20min or more), the more it wants to charge. I then have to add the hazzards in order to keep the charging state at normal. Sometimes it goes to no charge but not often. Any ideas?

You've got something in the wiring full fielding the alternator.
Check the engine harness where the wiring goes to the alternator. probably the hot lead is melted to one of the field leads.

Yoou may have to unwrap most of the engine harness, but it's usually near the alternator.

Well, I did find out that the part that was replaced was the Power Module and NOT the computer. I am pissed about that because I was told the computer was replaced. Replaced the EEC module this morning, it took care of the trans problem but not the overcharging problem. There MUST be a short somewhere. Gonna have to do some finding...
