The monitor panel for thor fourwinds 2013 not reading the batt, lps, fresh black and grey. Just the red emply light for all the above. I know there should have been readings from i.e. filling the fresh tank light indicated E empty. ect. All other switches on the panel work. i.e. hot water tank, Genny on and off.
tks in advance
I am not sure if the attached link to Ventline Monitor Panels information (now owned and branded by Dexter), will be of any help to you or not, but there is a section in the information for troubleshooting typical problems with these monitor panels. It might help you to check that your +12vdc and grounds are good to the panel first and then the wiring to the specific sensors and finally the circuit board.
