The problem as I see it.
Replacement senders don't have the QC and accuracy the factory ones did
There is no factory specs for these gauges anywhere that I'm aware. Maybe if "this was" 1970 and "you knew" one of the Chrysler engineers.........
The original voltage limiter was NOT a voltage regulator, but a crude pulsing device.
So all that is stacked against you.
