Looked up old wiring for the Princeton fuel probe. Might be of some help.

Princeton Fuel Probe

Postby Sonex1517 » Mon May 02, 2016 8:08 pm

Thanks

Apparently the additional wire is for resistive measurement.

I calibrated it yesterday, it seemed to work and showed the correct LED indications and the Belite fuel gauge registered full. I powered down, waited, powered it up, and the fuel gauge showed empty.

The Princeton probe LEDs still show the correct indication.

Back to square one.
