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.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
