Electrical gremlins? Traced, not guessed.

Today's cars run on wiring, modules and sensors. A single corroded connector or chafed wire can cause faults that seem unrelated, from a warning light to a window that won't move.

Kartech uses diagnostic equipment and circuit testing to follow the fault back to where it starts.

Electrical faults worth checking

  • Lights, indicators or the dash flickering
  • Windows, locks or accessories that stop working
  • Repeated blown fuses
  • A battery that keeps going flat
  • Warning lights that come and go

Electrical Repairs questions

Why do intermittent electrical faults take time to find?

Because the fault has to be present to be tested. Telling Kartech when it happens, such as when it's wet, cold or over bumps, helps narrow it down faster.

Can a blown fuse just be replaced?

A fuse that blows once can be a one-off. A fuse that keeps blowing means there's a fault in that circuit, and it needs to be found.
