Lost 12V Ground 1 circuit Interior Lights, Ideas on finding
While Changing out Vent fan Motor in Lavatory I lost power to the circuit. This also includes 5 other Overhead Lights on same circuit.
Fuse is not blown (I have a PD4645 Converter/ charger).
In running test with my Multimeter, IF I attach a temporary ground (Length of wire/alligator clips) to the Negative side of the wire intended for the vent fan to the PD4645 case (Only because this is the only close ground source I can find, I show proper voltage (12.6 Plus depending on PD4645 charge Mode).
Second Test I ran was measure voltage through the ground side of bad circuit I get 12 Volts measured on the ground side...... Isn't this an Indication of a shorted ground ?
When I attach the Temporary ground the 5 lights work as they should (I don't know about the New Vent Fan Motor as I have not tried to put back in operation).
For the life of Me I can't find the location of fault in either the Lights (I have pulled them out of the ceiling and the appear to have no shorted wires etc) OR the wiring I can access behind the fixtures.
I Have a PDF of my RV electrical schematics from Winnebago for my Motor home (WF324V) and I'm having problems finding the connectors on the wiring harness as they don't seem to be in indicated locations.
One question is do I simply need to re-establish a good ground on this 1 circuit without finding the Break ?
is there a easier way of finding the proper ground wire other than probing all the Ground wires (I know they are the WHITE colored wires) ?
Accessing the wiring within the ceiling not possible as is the wires for the circuit that I believe run from the ceiling down the interior wall. The bundle of wires appear to run under the bed which I have to remove to access. the wire bundle at this point appears to be 20 or more individual wires.
Open to words of wisdom
Getting ready for vacation next week and this is kicking my butt.
Thanks in advance
