Just got back. It is an alternator similar to Bob's picture but I don't see a number on it. Has a rubber plug where the two spade terminals are. I tightened the belt.
Battery was reading 12-13 volts and 12 volts at the alternator. Not really any change with key on and headlights on except new dash voltmeter showed 10 volts with lights off and 8 volts with lights on even though the multi-meter showed 12 volts.
Went to start it and battery was weak. Put the charger on for a while and it started.
Read 12 volts at the battery but the alternator was reading 42 volts. Headlights didn't make a difference except on the dash voltmeter. Ammeter didn't move much as usual. Checked and found a bad splice in the alternator wire. Cut it and hand twisted the two ends together for a temporary fix. Was only getting sporadic readings at the new splice and battery but nothing close to the 42v that shows at the alternator terminal.
Then I quickly shorted the #1 spade terminal on the alternator to the case with a screwdriver and got a spark. Then the alternator began putting out a steady 15 volts but I was getting a sporadic 12-15 volt reading at the battery. The dash voltmeter got just under 12v then and less with lights on. The ammeter was working now but varied from -10a with lights on to -5a with them off. Not sure what is going on here now with the negative amps but I do have the wire coming from the alternator hooked on the plus side.
Guess I'll buy some new 10 guage wire. Any ideas what I have now? Thanks.
