I recently purchased an Oday 272LE. I have a question about the DC wiring for the cabin lights, running lights, pressure water pump, etc. None of the items fed by the DC panel are working. I have checked the positive lead to the panel and the 30 amp fuse on the positive lead with a continuity test and it is good. The breaker / switches and steaming light switch all pass a continuity test. I suspect that I have a DC ground problem. The Oday 272s have the main ground and the negative leads all run into one bundle which is soldered and covered in black vinyl per the owners manual. I found this to be the case on mine. I am considering running a new 30amp ground to the panel from either the battery post or to the engine. Has anyone else encountered this problem? Is there something else that I could have overlooked?
DC Panel Problem on 272LE

This may be a naive reply, but have you checked your battery selector switch ?
Make sure it is on both for now...My only problems have been with the AC &
the GFCI system...good luck, Patrick

I agree with jibes that you need to do some voltage tests rather than just continuity. If you don't have voltage between supply and ground on the board, then check voltage between supply on the board and the engine block or other known ground to isolate the issue.
Thanks folks! I tried your suggestions but still no power. I did not read any volts. I tried running a ground from the battery to one of the cabin lights and it did not work. I also tried running a positive lead from the battery to the positive feed on the panel bus bar and still no lights.
When I first got my 272LE, my running lights didn't work either (I hadn't yet checked everything else). I came to find out that one of my batteries had a 2nd ground cable of a smaller gauge, that I hadn't seen and hadn't connected to the battery. Once i connected it, all systems worked fine. Before doing something dramatic, take a look around your batteries and see if there's a black cable within reach of the negative terminal that's not connected...
Thanks. I'll crawl under the battery compartment and see if there is a ground wire that is disconnected and pulled out of the battery compartment.
Thanks for the replies. I ran a temporary ground from one of my batteries to a wire that fed into the bundle of ground wires that are wrapped and sealed behind the dc panel and the wire instantly got hot and the insulation started smoldering, so I definitely have a positive circuit mixed in with the negative grounds.
