Bill;
That's what I was thinking. Either the altenator isn't putting out enough juice or I have a short somewhere. The truck starts right up so I don't see much movement at startup. As electrical items are turned on, the gauge dips towards discharge and just never recovers. The more I turn on, the lower it dips. Then it just stays there.
As far as I know, it is the original unit. The motor is not original. I believe it is a 78-79 250.
How would I polarize the altenator? Am I supposed to polarize it or is that a mistake? To check the battery voltage, should I put the positive lead right on the battery post and the other on a ground? Maybe I could then compare readings from there with readings taken at the altenator.
Obviously electical issues are my most pressing and difficult to wrap my mind around.
