I have been unsuccessful in make my fuel gauge reliable in my M15A-20. The over current contacts are shot. This is the two lead type where two resistive elements in the fuel sending unit control two bi-metal strips in the fuel gauge to control the pointer. The current in limited through the system by a set of contacts on one of the bi-metal strips. As the bi-metal heats up, the bi-metal strip opens the contact preventing over current damaging the fuel gauge elements.
I was thinking, why not short the contacts out and regulate the current with a voltage regulator configured as a current regulator?
Has anyone done anything like this or resolved the problem another way?
