I'll do another thread about what went wrong..... This one is just for the current issue.
Here's how my old alt was wired.
I connected B+/B- to the new alternator in the specified places, connected the
KEY SWITCH wire to I and the DUVAC wire to S. The 4th wire I assume is the tach and I connected it to the R terminal.
Now I don't have a tach. I seem to be getting good voltage (14.4) even at idle and there are no ALT related dash lights. My BIRD is working and my battery monitor shows the battery is charging.... So I think things are wired correctly except for the tach. Any thoughts?
