No the number one wire I was referring to was the one designated number one in the wire harness instructions.

Thanks, Jerry. I'll get a new one and go from there.

ALL RIGHT!! Got it in today and all is well with the charging. Bad alternator. Thanks for helping me through this. Now on to resolve the gas gage issue.

This is pretty simple.....The yellow wire goes to the (+) terminal on the ignition coil and is known as the exciter wire. It is the one that tells the alternator to go to work when you turn on the ignition key. The short red one needs to go to the 10/32 BATT stud on the back of the alternator and that is for the internal regulator to tell it what to do. Finally you should have a 10 gauge wire going from the BATT stud on the back of the alternator up thru the amp gauge then over to the starter solenoid where the battery cable connects. That will deliver the output from the alternator to the battery to keep it charged up....and you will live happily ever after. Randy

Ok here goes...The yellow wire should connect to the (+) terminal on the ignition coil and has the job of turning on the alternator when you turn on the ignition key to make it begin to charge. The short red wire in the plastic plug connects to the 10/32 stud on the back of the alternator marked BATT and is for the internal regulator so it knows what to do. Finally you should have a 10 gauge wire from the 10/32 stud on the back of the alternator that runs up thru the amp gauge in the dash then on over to the battery post on the starter solenoid. that is how the output from the alternator get to the battery. Do this any you will live happily ever after.....Randy
