Twelve-volt faults are where most owners give up, because the symptom and the cause are rarely in the same place. Heat shortens battery life here dramatically, converters cook, and solar controllers fail quietly - the panels look fine and nothing is charging. We trace it properly rather than replacing parts until the symptom moves.
Twelve-volt systems are where most owners stop, and reasonably so: a light that flickers, a fridge that will not run on battery and a converter that has quietly died can all present the same way. Replacing parts until the symptom moves is expensive and common. Tracing the circuit is cheaper and takes one visit.
Arizona shortens battery life dramatically compared with the spec sheet, and it is not gentle on converters either. Solar adds a quieter failure: the panels look fine, the controller has failed, and nothing has been charging for months while the batteries slowly cooked. Nobody notices until the rig is off shore power.
We trace faults before replacing anything, then handle converters, inverters, batteries, shore power and solar controllers. Appliance symptoms often turn out to be supply rather than appliance, slide motors that stall can be mechanical or electrical, and diagnosis is done at the rig.
Hot plastic smell, a hot battery or a scorched terminal means stop and disconnect if you safely can.
Long-stored rigs in Surprise and Apache Junction, solar setups around Peoria, and general 12-volt work across Phoenix, Mesa and Glendale.
How long does it take? Diagnosis is usually the visit. Repair depends on what it turns out to be.
These turn up on the same rig more often than not:
Rooftop air, absorption fridges, water heaters and furnaces - the ones that quit in July.
