Our 2003 FDTS40 Alpine coach 74777 has been giving us much pleasure.
The last trip had a small problem: The grey and maybe the black water tank readouts weren't working.
The 12VDC, fresh water, and propane readouts appear to be close enough...
The grey water didn't come up above the first light with at least 3/4 tank level.
The black didn't come up either but we may be only filled to 1/4?.
I checked the wires on the two tanks the best I could with no change.
I can't find any information on the manufacturer (probably the original 2003)???
Is there a test that I can run?
Is the two wire / level work on changing resistance of the stick on-strip? If so what wouLd the approx. resistances be for empty and full?
I would assume the reader is ok and the problem is either bad connections or the strips on the tanks have gone bad?
Where can I buy new strips if needed?
We are SENIORS enjoying going while we still can
We tow a 2008 Honda CRV
The coach has the 400HP ISL and 3 slide outs.
