With this in mind would it be a smart move to build a voltage divider, solid state and eliminate that weak point. If the circuit is fused that would give you the load required.
In the 50s car radios were AC because of the tubes; they had a component in the radio called a multi vibrator. It would act just as you described producing AC, a half sign wave. It is strange they would use this same technology in what I think is a pure DC circuit. Jest saying how it looks ..
Could it be that the component he is holding in post # 14 is really a Fred Flintstone self-resetting circuit breaker ( voltage regulater ), and the fact the he found it shorted could cause the sender to fry? With all the problems he is having I would, if it were me, ring out the wiring from the gage cluster to the senders. Simply remove the wire from the cluster side and the sender let them float, check for a ground on the wires with a meter.I have two brains, one is lost and the other is out looking for it
