Having an issue with alternator not charging.
Sorry if this has been covered elsewhere but could not find solution searching.
Issue might be two-fold. Not sure.
Dash battery light comes on when in ignition position number 2. It didn't at first when I started investigating problem, so I disconnected the wire at the D+ terminal at the alternator and jumped a connection to that exciter wire from the + battery. The dash battery indicator lights up when I did so. After that, the battery dash light will now come on after reconnecting the wire to D+ terminal. Alternator will still not charge after starting car. Dash battery indicator goes out after starting car. Battery is good and (more or less) fully charged.
So I decided to jumper directly from the battery + to the D+ terminal. Start car and the alternator does then work and is putting out 13.5 volts. But.....
It will only do so for about 10-12 seconds, then stops charging.
It will do this every time I try. It will charge for only that short period of time then stops.
This is will only happen if I jumper to the D+ terminal. No jumper, the car will not charge at all.
Anybody have any thoughts as to what I should be searching for?
Thanks for any input.
