Fuel Sensor

[Bandit 153]

Thanks for your replys. There are indeed two sensors for the three tanks in each wing in the Pennycap fuel sensor system. What I now need to know is how to determine if I am having a sensor problem or a controller problem.
The gages both come up to at least a zero reading and then fluctuate slightly between zero and 5 gallons. There is approximately 25 gallons in each wing.
The continuity on all the wiring checks good.
I have a couple of AP's helping on this however we do not know how to check the sensors without opening up the wings and tanks and removing them.
Anyone have any experience with troubleshooting the contoller and/or the sensors in the Pennycap system?
