# RV Wiring and Fuse Box Repair in Chino > OCRV Center repairs and rebuilds RV wiring and fuse and distribution panels in our Yorba Linda shop, from melted fuse blocks and chafed harnesses to wiring damaged in a collision or rodent intrusion. Diagnostics start at $285 and are credited toward an authorized repair. Wiring and the fuse box are where most RV electrical faults actually live. Years of vibration loosen connections, undersized add-on accessories overheat a fuse block, rodents chew insulation, and a collision can crush a harness behind a panel. We open up the affected run, find the damage, and repair it to the correct gauge and rating rather than patching over it. All work is done in shop at our Yorba Linda facility. ## Wiring and fuse panel work we handle The fuse and distribution panel is the heart of the DC system, and it shows wear in predictable ways: a melted or discolored fuse slot from a loose connection, a fuse that keeps blowing because of a short downstream, or an aftermarket accessory wired in without the right protection. On the harness side we find chafe-through where a bundle rubs a chassis edge, brittle insulation from heat, corrosion that has wicked up a wire, and rodent damage. We repair each to the correct gauge, crimp, and fuse rating. - Melted, corroded, or discolored fuse and distribution panel repair - Chafed, brittle, and rodent-damaged harness repair - Repeated blown-fuse short tracing and correction - Aftermarket accessory wiring corrected to proper gauge and fusing - Post-collision harness repair behind damaged panels and walls ## Repaired to rating, not just patched A wiring repair is only as good as the connection and the protection behind it. We re-terminate with the correct gauge wire and a proper crimp, restore the fuse rating the circuit was designed for, and protect the run from the chafe or heat that caused the failure. Twisting wires together and taping them over is exactly what we are usually called in to undo. Because we are a full collision, structural, and systems shop, we can repair a harness while the wall or compartment is already open from body work, then verify every affected circuit before the panel goes back on. A written estimate follows the diagnosis so you know the scope, and insurance is billed direct. ## Frequently asked questions ### My RV fuse keeps blowing, what does that mean? A fuse blows to protect a circuit, so a fuse that keeps blowing means there is a short or an overload downstream, not a bad fuse. We trace the circuit to find where the wire is grounding out or what is drawing too much, then repair the actual fault instead of just installing a bigger fuse. ### Can rodent damage really cause electrical problems? Yes, and we see it often. Rodents chew through insulation and can short or open circuits, leaving you with random failures that are hard to trace. We inspect the harness, repair the chewed sections to the correct gauge, and look for other damage they may have left behind. ### Do you repair wiring damaged in a collision? Yes. We are a full collision, structural, and systems shop, so we repair the harness while the damaged area is open and verify every affected circuit before closing it up.
