Lights flickering, windows dead, a fuse that keeps blowing or a battery that drains overnight? Electrical faults need methodical testing, not guesswork. We trace the fault to its source and fix it on the spot.

About this service
Fault finding is the hard part
Modern cars have dozens of control modules talking over a network, plus hundreds of metres of wiring. A single corroded plug or chafed wire can cause symptoms that seem completely unrelated.
We combine a diagnostic scan with hands-on circuit testing to find exactly where power or signal is being lost, then repair the wiring, replace the failed part or reprogram where needed.
