RV Wiring Repairs
[ad#block]  On our way to California, one of our 5th wheel tires blew. When it shredded, the tread tore into the undercarriage of the RV, ripping out some wiring. We no longer have electricity to any lights in our slide out. Our stereo in the slide out is receiving electricity, but the speaker wires were pulled out as well, so we have no sound. We have nearly no electrical knowledge, but we fed the wires back up through the hole they were pulled from, and attempted to reconnect the wires. They are color coded black and white, and through all of our attempts, we were unable to get the lights to come on. We changed out the fuse, and in the process of trying to reconnect wires, we blew the new fuse we put in. We’re thinking maybe we’re missing the ground wire, but we don’t see any wires sticking out anywhere, or any that don’t seem to have a match. If you think this is the ground, how do we go about locating the ground wire and where would we ground it to?

This electrical question came from: Brent, a RV Owner in South San Francisco, California.

Thanks for your electrical question Brent.

Electrical Repairs for RV Electrical Wiring

Brent, if this is the wiring for a 120 volt circuit then yes, there should be a ground wire. The wiring in the affected undercarriage area should be closely inspected and if there are any areas where the circuit wiring has been damaged then it will either need to be repaired or replaced in order to restore the power to the circuit.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    a friend removed a 12 volt dimmer switch and now does not know what wire went where. The switch has a red+(in) wire & black wire marked DC in and a red+ (out) wire & white wire marked DC out. Can you tell me how to wire this switch.

    I bought a used 2001 Prowler 5th Wheel. When we set it up the slide out goes in and out but the interior lights above the couch and table as well as the plug in do not work. We have tried turning the breakers on and off, and checked the fuses, tested the GFI plug. Is there anything else that may be wrong? Perhaps the junction box underneath the slide?

  4. Dave Rongey says:

    Hi Christine,
    After doing some research I discovered that Prowler RV Manuals and a Slide Out Wiring Diagram is difficult to locate. It would be best to have an electrician or RV service technician test the circuit breakers and fuses to make sure they are working correctly, as well as the GFCI outlet for power. The junction box located under the unit and the wiring should be inspected if all of the power sources look normal. It may be good to call the previous owner to see if they can provide additional information that would be helpful.
    I hope this helps you,
    Dave
