Factory ammeter

Mattax, thank you. I agree with your assessment. My choice of words was not correct on the soldered reference. Thank you for that. It seems to me that the welded section can be made cleaner by moving 1/3 of the wires to the vacant terminal. Here is the fuse panel as I am reworking it. I see now that someone makes a replacement box. ThxView attachment 1715695009
Unless its been damaged, the welded junction is going to make a much better connection than the push connectors.
If the welded junction has been damaged, then a good repair such as an in-line soldered crimp splice would be my first choice.

Do you have any idea what caused all the damage?
The hot buss is usually just brake lights, parking lights, dome and hazzard.
Everything else is usually on the switched buss.
The middle fuse holder that you repurposed was the optional/accessory fuse. It could be for A/c or the rear defroster or a tach.
