Chev fuel tank sender

[Jim Burrill]

My old C-15A had one ford tank and one Chev tank. Of course the senders didn't cross match, so I had to have one Chev and one Ford sender, but they needed to both go into the same gauge.

Of course the ohms were different between them, so a full Chev tank reading looked like 1/4 tank when switched ot the Ford tank.

I had to add a resister to the lower circuit ( can't remember now) and then calibrate it to work with the chev gauge. I believe I used a small potentiometer to tweak the settings.

Any one else run into this situation?
