Any ideas before I capitulate and buy an new alternator? Has anyone ever had the actual
Gauge go bad?- I have a spare instrument cluster So far:
Belt routing- check
Connector on back of alternator- stripped and crimped a new connector- this worked for 1.5 days….
Voltage:with the lights on, cell charging and jimmy hendrix’s cross-town traffic at an obscene level- still 14.5 at the battery….. the alt problem has been ongoing for about 6 months now… if the alt was going to fail it would surely have done so by now would it not?
Tach works intermittently first thing in the morning- belt is 10k new- possible stretch?
Are there any voltages out of the back connector to check? An old post mentioned a resistor- the Haynes doesn’t have the ohms for this…. Help appreciated… unless you’re my alternator part supplier.
Cheers
peter

My connector comes loose all the time. I wanted a new high output alternator, but unfortunately mine's still fine :-(. I just have to clean the terminals and reconnect them securely. When it first happened I put a multimeter across the back to verify it was working properly. I don't remember where I put it across, but I do recall experimenting a bit before I found the right places.
