rear alternator light

[Mark Hislop]

More than likely is that you've got a blown diode on the little signal processing board on the top center of your firewall. Or possibly a bad relay on the same board. The diodes are very easy to replace. I would disconnect them one at a time and check them first. There are a total of 4 of them, 2 for the front engine, and 2 for the rear engine circuits. There is one relay for each circuit. There is also a fuse for each circuit.
