I can not tell from your answer whether you appreciate that the ammeter indicates Battery Charge and Discharge.
Even though Chrysler labled them 'alternator', they do not show alternator discharge.
They only indicated electrons going into or out of the battery.
If the battery is discharging when the engine is running, something is wrong with the alternator or alternator circuit.
Look here. If you can follow a map then you can follow this.
For example in Dana's first video, the engine is off, the key is turned on, and the turn signal is on.
Take your finger and trace the path of electical flow from battery positive to the turn signal flasher.
Now lets say the engine is running and the alternator is producing power around 14 Volts.
Take your finger from the alternator terminal marked BATT and follow the path to black circle.
Continue along a path to the key switch. That's the path to everything requiring the key switch on. How much current went through the ammeter when power is coming from the alternator?
Go back to the junction represented by the black circle. Follow the route to the battery.
This is the electricity needed to recharge the battery
The BATTERY MUST BE CHARGED before going any further in testing and experimenting.
A low battery, or a damaged battery will draw excessive amount of current through the wiring.
This can confuse the diagonses and will cause damage to the wiring, the connections, the ammeter, and the battery.
The ammeter reads 40 amps Discharge to 40 amps Charge.
So if by three quarters you mean 3/4 of the way between center and Charge, that's about 30 amps. That's alot!
On this old charger 40 amps is the beginning of the red zone
Do not use the alternator to charge a battery that is severely discharged.
And considering that its not charging normally - we think that's a likely possibility.
