67 Barracuda Heavy Electric Load
I dropped the alternator off at Auto Electric Systems in Dallas. They had planned to test while I waited but the person running the tester had left for the day and will get to it tomorrow morning. They asked lots of good questions and seem to have the correct equipment to get a good test.
The electric fan does not kick on until 180 degrees so it takes 5 to 10 minutes after starting to kick on. So the Alternator gage picks I posted this morning did not have the fan running.
I have noticed an occasional alternator belt squeak right after starting but the belt seems adequately tight. Will definitely make sure it is tight when reinstalling an alternator (maybe new) tomorrow.
