No power.. Ammeter questions.

Thank you for a fast reply!
Just a twist a fate I noticed it. :) Just got in from working the polls and took a quick look at the forum.
Yeah both red and black wires are corroded and I’m gonna fix that. And if I get a new Ammeter like an aftermarket one I can just hook it to those two wires right since the board itself is just a support?
You can if the old one is really dead. Aftermarket ones used to be common. Instrument repair place may be able to fix the original.
I thought it was part of the board.
The copper you see laid on the back of the board - those are circuits. For example the one immediately above looks to be instrument lighting and the black plastic is the bulb holder.
Why the ammeter is seperate should make more sense when you look at the circuit diagram I linked to earlier. Basically its job is simply to indicate how much current is flowing into or out of the battery.
