I assure you all that I have my facts correct. The amp meter gauge will fry if not protected from a 105 amp alternator trying to charge a dead battery.
It's an old car and not the best wiring engineering.. The gauge is protected while cranking the starter with an ignition disconnect.
The current from the alternator goes directly through the gauge and then to the fuse box. Without the gauge the car has no power.I will see about posting a wiring diagram later.
Well a dead battery can't start the engine so the alternator will never put out any current. Charge the battery with a battery charger and then you can start the car and it won't try to draw 130 amps from the alternator because the battery is no longer a dead battery.
