Michael, Thanks for the tip. I'm on my way to the garage to check this out. Lupe ----- Original Message ----- From: "Michael O.

Use an ohmmeter to test resistance between the connection on the outside of the unit, and ground. If it's like the A=bodies, you should see between seven and 70 ohms resistance. At the lowest point, as with the tank nearly empty, resistance should be highest, around 70 ohms. If you raise the float to mimic a full tank, resistance should drop to around seven ohms. Good luck.
