I no longer have have my Class A Motor Home. In going through "STUFF" I found this;
Fluid Sensor Part# 500118 (at least that's what it says on the bag)
It is the float used in the hydraulic tank for the levelers, I replaced it but it turned out that was not the problem (it was low on fluid) DUH
Here is what it says on the top of the instruction sheet I got..
T.I.P. Troubleshooting Information on Power Gear
FLUID SENSOR REPLACEMENT PROCEDURE
For kit no. 500119 and 500299 and in my hand writing 500577
If you want it let me know and I'll mail it to you. PM me your address and I'll get to you....
