Common auto electrical jobs in Hornsby
Hornsby is where the North Shore and Northern railway lines meet, and the M1 Pacific Motorway starts just up the road in Wahroonga. That makes it a base for both commuters and Central Coast or holiday trips, with bush pockets west of the Pacific Highway adding their own problems.
Commuter cars that will not start
Cars that sit all day near Hornsby station and only do the short run home are prone to weak batteries. Hot days in an open car park speed up the wear. If the car cranks slowly in the evening or the dash flickers on start, get the battery and charging system tested before it leaves you stranded. Our guide to is it my starter motor or my battery helps you tell the two apart.

Brake controllers for M1 trips
With the motorway so close, many Hornsby caravan and camper owners head straight north. Any van with electric brakes needs a brake controller in the tow vehicle, set up to suit the van's weight. A controller that is set too low makes the car do all the stopping, while too high locks the van's wheels. If you are fitting one yourself, follow how to install an electric brake controller.

Bushland rodents
Streets on Hornsby's western side sit close to bushland and parks, and rats love a warm engine bay on a cold night. Chewed sensor wires or a gnawed loom can cause odd warning lights that come and go. Repairs should use proper solder or crimp joins and heatshrink, then loom tape over the top. Keeping the garage free of pet food and bird seed removes a big part of the attraction.

Headlights for night motorway driving
Driving up the M1 after work, especially through the dark bushland stretches north of Sydney, shows up weak headlights quickly. Old halogen globes dim with age, and cloudy lenses cut the light further. New quality globes, replaced in pairs and aimed correctly, make a noticeable difference. For trucks and vans doing regular night runs, LED driving lights are an option, wired through a relay and switched with the high beam.

Charging system checks
A battery light on the dash while driving up the Pacific Highway is a warning not to ignore. It usually points to the alternator, its drive belt or a wiring fault between them. The car will keep running on battery for a short time, then die. Turn off unneeded electrics and head home or to an auto electrician. Our article on the battery warning light while driving explains what to do.

Hornsby auto electrical questions
My car sits at Hornsby station all day. Will that flatten the battery?
Not on its own. A healthy battery copes easily with a day of parking. Problems start when the battery is old, the trip home is short and the car never gets a long run. Add a dashcam in parking mode or a faulty module and you can come back to a dead car. A battery test is quick and cheap.
Do I need a brake controller for my camper trailer?
It depends on the trailer. Light trailers often have no brakes or override brakes that work without a controller. Trailers with electric brakes need a controller in the car to work at all. Check the trailer's compliance plate and brake type, and follow the towing rules in the state handbook.
Local tip for Hornsby
Before a long trip up the M1 with a caravan or trailer, plug it in at home and walk around it with someone working the lights: park lights, both indicators, brake lights and reverse. Check the van's battery is charging while the car is running. Finding a fault in your Hornsby driveway is far easier than finding it at a rest area at night.
