Electrical diagnostics & charging systems
Alternators, starters, wiring faults, and module communication issues — traced with wiring diagrams and test equipment.
Dim lights, slow cranking, or random warnings can stem from charging, grounds, or failed modules. We avoid unnecessary alternator swaps by proving failure mode first.
Corroded grounds and rodent damage are common; we inspect harness routing during diagnosis.
Complex faults may take extended time — we’ll checkpoint with you before digging deeper.
