Most Charger Problems Are Not the Charger
EV charger repair and troubleshooting in San Clemente is the service where we see other people's work, and the pattern is consistent enough to predict. When a charger trips its breaker, throws a ground-fault code, or delivers half the amperage it should, the cause is almost never the charging unit. It is undersized conductors, a shared neutral, a loose lug that has been heating for a year, an unbonded ground, or a charger configured to draw more current than the circuit was built for. Along the coast we add a sixth cause: corrosion at a termination or inside an enclosure that was never rated for salt air. San Clemente EV Charger tests the circuit, shows you what we find, and corrects it to code rather than replacing the hardware and hoping the symptom moves on.
What a Repair Visit Covers
Symptom interview and fault-code reading
We start with what the car and the charger are actually reporting, because a ground-fault code, a thermal derate, and a straight breaker trip point at three different problems.
Circuit testing under load
We measure voltage, current, and voltage drop with the circuit under real charging load, which is the only condition in which most of these faults appear.
Termination and lug inspection
Every termination from the breaker to the charger is opened, inspected for heat damage and discoloration, and re-torqued to specification or replaced.
Conductor sizing verification
We confirm the installed conductors are actually rated for the breaker and the charger's configured output, since undersized wire behind a correctly sized breaker is a common and dangerous shortcut.
Grounding and bonding correction
We verify the equipment ground is continuous, correctly terminated, and not shared with a neutral, which resolves the majority of persistent ground-fault codes.
Breaker testing and replacement
GFCI and standard breakers both fail, and a weak breaker that trips below its rating is easy to mistake for a wiring fault. We test rather than assume.
Charger amperage reconfiguration
Where the unit is set above what the circuit supports, we reconfigure it to the correct value and explain the trade-off in charging speed.
Corrosion remediation on coastal installs
Corroded terminals, enclosures, and fittings are replaced with corrosion-resistant equivalents and resealed, which is routine work west of the freeway.
Charger replacement when the unit has genuinely failed
If testing shows the hardware itself is dead, we advise on warranty status and install a replacement, reusing sound circuit work where it exists.
Correction of unpermitted prior work
Where a previous install was never permitted, we can correct it to code and bring it through inspection so it is on record.
How We Diagnose and Fix It
Diagnosis on site
We arrive, read the fault codes, and test the circuit under load. This is a diagnostic visit with a defined fee, not a guess, and it typically takes an hour to ninety minutes. You see the readings and the photos of anything we find inside the panel or the enclosure.
Findings and options
We explain what is wrong in plain terms and quote the correction flat-rate. Where there is a choice between repairing the existing circuit and rebuilding it properly, you get both numbers and an honest recommendation about which one will still be fine in five years.
Correction and verification
We perform the repair, then charge your vehicle on the circuit and confirm it holds full rated current without tripping, without derating, and without heat at the terminations. Where the original work was unpermitted, we can bring the corrected circuit through inspection so it is documented.
Why This Fix Sticks
We test before we replace anything
Swapping a charger to chase a fault is expensive and usually leaves the real problem in the wall. Diagnosis first means you pay for the repair you actually need.
You see what we found
Photos of the corroded lug, the undersized conductor, or the shared neutral come with the quote. You should never have to take a contractor's word for what is inside a wall you paid them to open.
We can put it on permit afterwards
A previous unpermitted install is a real problem at resale. Once corrected, we can carry the circuit through inspection so there is a record showing the work is compliant.

Get Your San Clemente Charger Diagnosed
A charger that trips the breaker or charges at half speed is telling you something about the circuit behind it, and ignoring it does not make it safer. Book a diagnostic visit and find out what is actually happening.
