RV Electrical Repair
in Austin

Electrical faults are where guessing gets expensive. An RV runs two systems at once — 12V DC from the batteries and 120V AC from shore power or a generator — joined by a converter or inverter, and a fault in one often shows up as a symptom in the other.

Typical work

• No 12V power anywhere, or lights dimming when the pump or slide runs
• Converters not charging, or charging but not holding
• Inverter faults, and inverters that shut down under load
• Batteries that will not hold a charge, plus lithium conversions
• Shore power problems — pedestal, cord, transfer switch, or the rig's own panel
• Dead outlets, tripping breakers, and GFCI faults
• Chassis and trailer wiring, including lights and brake controllers

Heat and batteries

Austin summers are hard on lead-acid batteries. Heat accelerates water loss and shortens life considerably, and a battery that tests fine in March can be marginal by August. If several unrelated things started misbehaving at once, suspect the battery bank before the individual devices.

One safety note

A hot skin — any tingle when touching the rig while plugged in — is a genuine electrical hazard. Unplug and call. Do not keep using it.
