RV Electrical – Check for proper wiring at campgrounds. If you search the Internet and read RV forums much, you will run into stories where folks have ruined RV appliances because The campground’s wiring was improper or because the campground’s voltage dropped below safe levels or surged above safe levels. Occasionally you will run into stories of people being shocked (or worse) due to incorrect wiring of the campground pedestal.
How do you combat this?



On September 12, 2013 Sharon and I were headed to Woodward, OK for my High School Reunion, class of 1959. About 9 miles short of Seiling, OK on US Highway 281 at the intersection of OK Highway 51 Sharon was driving and stopped for a Bathroom Room Break as there was a picnic area there. I went to the bathroom first, and Sharon started screaming “Fire”. At this point we had been on the road for about 5-hours with the Tom Tom GPS hook up to a 12-volt plug in the dash, that was the only 12-volt electrical plug being used that day.

When the failure occurred we had a TomTom GPS hooked up for about 5 hours to the 12-volt electrical plug that the wire burned through. You could hear a fire going but could not see any smoke, so I grabbed a fire extinguisher and ran outside. The cabin filled with smoke, and when I could not find a fire outside the coach I came back in and looked under the dash. The wire bundle was shorting to a screw in the firewall with a lot of smoke and sparks. When I pulled the wire bundle away from the fire wall the shorting quit. When I released the wire bundle again the sparks started flying again.

I cut the electrical tape around the wire bundle so that I could pull it away from the firewall and the screw it was shorting out against. I told my wife to start the coach, but the starter did not work anymore, and some of the dash and clearance lights could not be turned off.

When the coach was brand new we had problems with the 12 volt plugs shorting out. The dealership just replaced the fuses and gave us some extra fuses. The problem was intermittent with the circuit shorting out every two or three thousand miles. I just continued replacing the fuses.

When the failure occurred it appeared that the screw with a sharp point at the end coming through the firewall had wormed through the outer covering shorting against the wires. When the coach was assembled the wire bundle was tied against this screw which after 30,000 rubbed through the outer covering shorting out.

Based on what I saw at the time, I think the screw wore through the outer covering and shorted everything else out. If you look close you can see the electrical tape that I cut to pull the wire bundle away from the screw. Also, how the outer cover was melted where it contacted the screw in the fire wall.

I recommend a design change so the pointed screws through the fire wall are not tied against the wire bundles. I am not sure what the purpose of the screws are but why have pointed ends? This creates an abrasion point to ware through the outer wire bundle covering and short everything out.

Failure Analysis:

I do not believe that the 12-volt wire could have shorted out and burnt everything up like what happened. Notice the 12-volt wire at the plug had completely failed burning through disconnecting the wire from the ground. In order for this to happen the 12-volt wired had to be getting power from somewhere else besides from the designed circuit through the fuse. I would deduct that the fuse is probably not blown because that is not where the power was coming from.

When the wire bundle shorted out, negative wires became positive and positive wires became negative. Switches and circuits were by-passed; and that is why some of the lights could not be turned out.

I assume that the wire bundle has some large wires that can carry a lot of amps, and that is why everything melted. A 12-volt cigarette lighter plug wire cannot carry that much power.

I drove back to Oklahoma City from Fort Worth, TX to take photos of the failure as Rush Truck Center could not find the short against the screw in the firewall. See the photos attached and the videos were too large to email so they are on Youtube and Facebook.
