Welcome to Overhaul Auto Electrical

We’re a Mobile Auto Electrical Service that covers all of Sydney - look no further for a local auto electrician.

We specialise in 12v and 24v accessory installations like driving lights, dual batteries and dashcams. Anything your 4WD or caravan could need while camping, or if your tech breaks down, we diagnose and repair too.

The more custom the job, the better! Our creative team will tailor make the installation or repair to your needs and ensure it’s working the way you want it!

Best of all, as a small business we don’t charge an arm and a leg, we can work out a price that fits within your budget, have a chat with us and find out why people love us!
