YJ/CJ Fuel Gauge Compatibility ?\'s
Hey everybody. I'm almost done with my CJ dash swap.. I've wired everything, everythings bolted in - with the exception of the fuel gauge.
I remember reading somewhere that the resistance values for a CJ and YJ are pretty close to each other - only they're flip-flopped... IE a YJ might be like 0 ohms @ full, and 80 ohms @ empty. A CJ, on the other hand, would have 80 @ full and 0 @ empty.
Does anybody have these exact values? If they're pretty close to being a dead-on flip flop, i can just reverse the leads on the back of the gauge, correct? That will send power to the opposite magnet in the gauge, thus swinging the needle in that direction...
Any help is greatly appreciated.
