Mobile Auto Electrician

$150

Coogee NSW, Australia

9th Apr 2026

🚗 Mobile Auto Electrician Needed - We believe there could be an Electrical Fault (2004 Toyota RAV4) Looking for an experienced auto electrician (not general mechanic as we just had a general mechanic out who couldn't solve the problem) to diagnose and fix an electrical issue. Vehicle: 2004 Toyota RAV4 Location: Coogee We just had a mobile mechanic out, who has suggested we need an auto electrician. Issue: Initially was alternator wasn’t charging. It was odd because the alternator and battery had changed less than one year. I bought a new battery from the NRMA, which just went flat on a long drive. It was driving fine once I charged the battery up. But when the mechanic came to look, the - Engine cranks but won’t start - Cylinder 2 & 4 ignition coils not firing - Low voltage at ECU trigger wires to coils - Previously had intermittent charging issues - Alternator behaviour has been inconsistent - Diagnostic tool previously struggled to connect What’s already been checked: - Battery replaced (new) - Fuel pump working - Fuses checked (all OK) - Continuity from alternator to battery OK - Alternator exciter wire previously had 14V, then 0V - Ground cable visually inspected (may still need proper load testing) - Spark issue identified on cylinders 2 & 4 What we need: - Proper electrical diagnosis (ECU power/ground, wiring, voltage drop testing) - Someone experienced in wiring faults, ECU circuits, and ignition systems - Not looking for parts replacement without diagnosis - Thinking maybe something up with the key and sending the signal to start as the spare key behaves similarly. Please only respond if you: - Are an experienced auto electrician - Have diagnostic tools (multimeter, etc.) - Can trace wiring/voltage issues (not just swap parts) Thanks!
