Fresh water tank gauge sender

[Bob Dunahugh]

Is there an OHM reading when empty on a 73. That will give me a hint of it's condition? Water system seems to be tight. The water pump works fine. But don't want someone to have it quit on their first trip. So I put in a new SurFlo pump. Still think I'll have it for sale next week during the Amana event. Bob Dunahugh

Bob,
All the gauges used in the GMC coaches were 0-90 Ohms units and that included the water and black water tanks. Here is a good site for checking and troubleshooting gauges.
