Dinghy Battery Charging
2013 Holiday Rambler Endeavor 43DFT
I am trying to find the source for the 12V charging lead in the 7-way connector factory mounted on the rear of our motorhome. I suspect it must be fused somewhere.
Part way thru our winter vacation last year the battery on our toad/dinghy began to quit during the day while being towed. The wiring had been set up to charge the dinghy battery and it was working. I checked the pin (1 o'clock) on the 7-way connector and found there was 0 volts with the engine running. The 7-way has a 3 foot pigtail with a 6-way flat connector and a single lead for the brakes. The 6-way has white,black,red,brown,green and yellow leads. With the engine running there was 0 volts on the black lead coming from the coach. I suspect there is a fuse blown somewhere. The 6 wire pack disappears into other wire packs running under the chassis.
I have discussed with Monaco techs and they do not know the source for this circuit. They sent me schematics of 2012 HR but I cannot find any reference to the 7-way connector wiring. I checked the front DC fuse panel in the left front bay and could not find any reference to trailer/dinghy charging. I checked the owners manual which has drawings for this DC panel. I checked the inline fuses located in the right rear compartment with the chassis batteries and there is no reference to dinghy charging. I checked in the compartment housing the Bi-directional isolator but no reference to dinghy charging. I have checked around the converter located mid-bay passenger side but no reference to dinghy charging. I must be missing something.
Has anybody run across this wiring and is there anybody that knows where the charging wire originates?
