Modern vehicles are rolling computers, and electrical issues are where a lot of shops tap out. Not here — Toyota master and ASE master certification includes the electrical side, and we have the tooling to actually trace a wiring problem instead of guessing. Parasitic draws, intermittent no-starts, strange module behavior, after-market install problems — bring it in.
We handle the usual suspects (battery testing and replacement with correct CCA and proper registration for smart-charging systems, alternator and starter diagnosis and replacement, relay and fuse work) and the harder stuff: wiring-harness diagnosis, module communication issues, parasitic draw tracing, chasing down an intermittent on an oscilloscope when the code reader has nothing useful to say.
Old-school electrical work on modern vehicles means actually reading the schematic, testing the circuit the way the factory intended, and verifying the repair with a meter — not a shotgun of replacement parts.
