Cuda overcharging? Please help...

I bypassed the ammeter today to see if it made any difference and also just because it's safer that way... Gonna go multimeter shopping tomorrow and see if I can pinpoint the source of the problem... I know a lot of those wires are looking pretty old. I would like to rip it all out and redo all the wiring someday but I need to overcome my fear of auto-electrical first haha

Hey player1up, I see you live in Orlando. Do you ever stop by the cruise nights at OldTown in Kissimmee?
