Factory ammeter

This is a drag car and making repairs to the wiring harness w/o replacing it. Aside from the fuse block melt. I have replacement fuse terminals and 90% of the harness is good. Getting the car up and running with a 440. I moved the melted terminals to the 4th terminal since I deleted the rear window defrost and headlight buzzer wiring.

Then the factory harness should be plenty adaquate assuming this is not an EFI conversion.
So the only things the alternator really needs to do is run the ignition and recharge the battery after starting.

Here's what the flow would look like if the car is running and foot is on the brakes.
