I recently bought a 91 crown vic ex-cop car off one of my friends thinking that it only needed a alternator, but found it is more then just a alternator. I have replaced the alternator and the external voltage regulator but I am still only geting 10 amps to the battery. I have tried 2 new voltage regulators, used 2 different batteries, and checked the grounds, cleaned the battery terminals, took the battery clamps off and cleaned the corrosion off the ends of the wires and still only 10 amps to alternator. I have disconected the voltage regulator and jumped the A and F slot in the harnes with a piece of wire and got 13.5-14 volts at idle. I dont know what to do from here. Could a bad wire or fusable link be causing this problem? Also the starter has been replaced recently.
