Just dropping a note due to a problem I averted that may help others.
My 73 Cuda was rewired by a resto shop and the ammeter never worked when I received the car back, despite paying for a new ammeter.
4 years later I finally decided to tear dash apart and find the issue.
First I noticed the original ammeter wires provided in the kit were no longer on my car and instead two red 10gauge wires had been installed...clue #1.
Tracing one red wire, led to the 70amp fuse in the engine bay however there were two wires on the one spade terminal, where only one wire should be ...clue #2
Tracing the second wire back into the car, led to the internal fuse block buss...interesting and clue #3
Tracing the opposite side of the ammeter led me back out to engine bay to the hot battery side of the ignition relay...yikes!...clue #4
Conclusion I had no fusible link between the engine bay and dashboard...it was hot wired 24/7 yikes!
Solution: following the Cuda factory manual, rewired correctly and ammeter works!
Just to be sure I pulled the 70amp fuse with the car running and car died
So for those with a dead ammeter that been rewired, maybe take a look in that dashboard
