I have my old faithful 806 diesel with the alternator just started heating up. It's charging at 19 volts so the lights got bright and burned out.
I did some research on the forum here and found the bottom wire on the plug in at the back of the Delco alternator was the sensing wire for the battery voltage. When I checked the wire at the plug it has no voltage with a good battery and the switch on. The other wire is said to be the exciter wire so should it be showing voltage with the key on?
Would that make the alternator overcharge and heat up? I saw one diagram for installing one of these and he had come straight off the battery feed wire at the back of the alternator and ran that directly into the 2 wire plug.
Would that likely fix my problem?
Thanks a lot, as always, Bob
