Also make sure you check voltage at the alternator and make sure the ground it attached from the alternator to the block. Is this the original alternator? Brushes/voltage regulator could be gone on it.Has the battery been charged and checked? If the battery is good and the alternator isn't charging. You next want to check that the charge light circuit is providing 12v to the alternator D+ terminal. Make sure you have it on the proper spot.

After finally getting my 240's charging to work properly, first question: Does the battery warning come on with the key on, engine off?
I've usually been able to breathe new life into a Bosch alternator for my brick by replacing the voltage regulator in the rear.
Simple to do; the problem typically turned out to be worn brushes, which the replacement voltage regulator replaces with new ones.
Yep. Much better than putting some aftermarket reman junk in your car that has probably failed once before in it's lifetime. Easier too. Good point!
Or pick up a nice 100A Nippon denso alt
New issue, d+ has power when key on engine off but when key on engine on theres no power any ideas or anyone have access to wiring diagram
It's normal to read, like, a volt on it when running if it's connected. Disconnect it and it would be another story. Whats the issue? No charge? Is your ground wire OK? Belt tight? Slap 12v to the exciter terminal manually once per engine start to determine if it's an exciter circuit issue or not.
