I have a 68 C model with bladders and CiES sending units. I had the same issue with one tank (L/H) showing full all the time. I removed the side panel (after troubleshooting with meter) and found the sending wire loose on the sending unit.

Sent PM to 803RM.

New owner so have some compassion. I purchased a 1968 M20C that had been sitting for some time. After getting it flying one of the fuel gauges shows full all the time (which was how the plane had been stored for an extended period of time ). The question is has anyone seen these indicators start working after being put back into service after an extended period of storage? Described on this forum was a good description of how the indicator works with the wiper across a small coil and I was wondering if the assembly just needs to be moved around to come back to life. The airplane has the O&N bladders. Thanks Old Chub

Jetdriven, Thanks for the photos. as they say a picture can describe a thousand words. I will start working on a like bracket for the flux valve (not to be confused with the flux capacitor) Old Chub

Thanks to all that replied. Great information. Jet Drive = I am installing the same thing. A Sandel 3308 Greg Ellis = I am at Hicks Airport. Just move over from GPM last week. My Cessna 120 is also there at Hicks.

I understand the gyro is mounted on the avionics shelf in the back but were is the flux valve. This item is approx 3 to 4 inches in diameter and appox 3 inches tall with a rounded cover..

New Member here and this is my first time using so here goes. When installing a remote compass for the HSI in a pre J model Mooney where do installers usually mount the flux valve (Magnetic Azimuth Transmitter) Honeywell KMT 112? Thanks Old Chub
