DC Electric problem

I have 2009 Greyhawk 31GS. I am not getting voltage to a couple of my 15amp fuses. I am not sure where the fuse panel gets the voltage from. I m fearful that I may have a converter problem, however most DC items are working.. Any suggestion

Thank you
Tobster

The power side is normally a common buss. Very doubtful that it would be the converter.

Find the GFCI plug and check it to see if it has tripped. Should be near/in the kitchen or bath.

The GFCI is located in the Bathroom. I did check that and seems to operating properly.

Thank You for your reply

After checking all the fuses they all test good. The only circuit I am having an issue with is called "Monitor, Kitchen area, water pump." The Control Panel, the light above the sink, and the switch in the bathroom for the water pump are dead.

Thank You

Ok, Lets start at converter,

First GFCI has nothing to do with 12v power. That is the 120 side.

Your battery supply's 12v to the converter. You will see at your converter 2 thick gage 12v wires coming in and mounting at two terminals. Usually white and black or black and red. These terminals power the 12v fuse buse. Sounds like all this, is ok since you have 12v power to other things.

You found the circuit you are having problems with, but you said the fuse is good. So you must have 12v power from bus to the out side of converter. On the back of the converter there will be a wire bundle. There will be a connection there at each wire comming out. Check that connection. Even if it looks good. There will be plenty of excess wire. Cut it after connection and see if you have 12v. If not, you found the problem. Redo the connection. This is actually common. The problem is finding the right wire to the circuit. Somewhere on the converter there should be a wiring diagram. Like brown/green #4. That means #4 fuse powers brown/green wire. Hope this helps.

If this is not the problem and you have good power coming out. Its time to trace that wire. This can be a #@#@#!!.

I miss read your problem,

Your saying that some of your fuses are not getting 12v power. Are these fuses located on the converter panel? If so, this is very uncommon and would mean the bus has somehow came apart and that would be a new converter.

The fuse panel is located in the bedroom on the outside of the bed stand. under the bed is where all the electronic nightmare is. converter, inverter, etc. is located. After testing more, it appears that only that one circuit is not working, and it does appear that the 15amp fuse is good.

Thank You

Remove the fuse that powers the bad circuit. Check for voltage at the fuse slot--you should get 12V on one side. If you do, there' s nothing wrong with the panel bus.

Are you sure the fuse is good? Try swapping it out with another 15A fuse on another circuit.

Assuming the fuse is good it is then time to remove the panel and start checking wires as stated above. You'll have to make sure there is power at the wire that is designated for that circuit to rule out any problems in the panel. There may be a crimped on wire connector (similar to a wire nut) where you can stick a probe into without cutting anything to start with.

Good luck!
