Reply #16 – August 23, 2010, 04:04:41 PM Quote from: shameless;332657mine has 3 wires on it, looks factory, but could be someones hack job.If your car is really an 84 that someone swapped an 85 or 86 instrument cluster into, that would explain the 3 wires on the alternator. It may also explain why it doesn't work.When you have a battery light the wire that is hot with the key on goes through the battery light before it goes to the voltage regulator.Can you post your VIN number?
