I moved my battery to the trunk, and ran 0 cable to a Moroso battery shut off, then about 7 feet were I used a junction block, that reduced it to 4 gauge that goes to the starter, where the alternator piggyback. I am running a 140 alternator single wire. Well tonight was the first night that I used my lights and after around 40 minutes of driving I noticed my volt meter going down, I just barely made it home, what did I do wrong. After I charge the battery overnight I will check the voltage at the alternator and see where it's at. I have a new harness from M and H, that harness worked before I did the restomod. It would show 14 volts, now it only shows about 12.5 (battery potential)??????????????......................................Mark
Charged battery over night, only charged to 12.5 volts..boy was it dead, it was so down last night my C2 gauges have LEDS and they were almost dead, LOL. Well started it this morning and checked the alternator and was only putting out 12.55 ( battery voltage) I might have a bad alternator. What would I look for as far as the field wires....................Mark
Vikki I don't know if the 2 wires that go to the alt would be the field wires? They are in a two gang plug that goes to the side of the case, when I ordered the harness from M and H I told them that it was a one wire. I am still trying to get pics of car to down load, Anyway I called Tuff Stuff yesterday and they are sending out a new altnator, should be here Thurs. will let you know what I find out after I hook it up. Sounds like it was a bad out of stock..........Mark
Yes, the two wires on the harness would be the field wires, and therefore operating as a three wire alternator if plugged in. If plugged in, the voltage regulator must likewise be in place and plugged in (if externally regulated).
Was the alternator designed as a one wire alternator?
