Charging issues
89 Bronco II 2.9 Eddie bauer
I noticed today that my battery light is on, the gauge shows it is still charging. The needle will show a little discharge but as soon as I give it some gas it will climb up to where it has been prior to this. When the head lights and/or heater fan is on it shows alot of discharge untill I get the rpms up to around 2000 I went to the Haynes manual for help. It gave me some ideal what to do.
First I have used 2 different battery in it one is new and still had the same problem.
The book said:
to check all connections- done everything is good, belt is also new and tension is good.
To disconnect the alternator wiring harness and see if light goes out or stays on- Do I disconnect both plugs? If I disconnect both the light goes out, meaning bad alternator, if I disconnectthe bottom plug light stays on, meaning short some where. Book said if light stays on then start pulling fuses to find the short out circut. Do I do this with the harness disconnected or connected? With it connected I have pulled every fuse on the BII and nothing changed. I have checked the ground wires and every one of them looks good. I have not found any fusible links the book talks about yet.
Electrical is my biggest weak point, any ideals where to go from here or am I doing something wrong.
Thanks
