Before you work on vehicle electrics
- Disconnect the negative battery terminal before working on wiring, and reconnect it last.
- Replace a blown fuse only with one of the same rating. If it blows again, there is a fault to find, not a fuse to upgrade.
- Many newer vehicles have a battery management system. After a battery change, some need the new battery registered with a scan tool so it charges correctly.
- Hybrid and electric vehicles have high-voltage systems, usually with orange cables. Leave anything near them to a qualified technician.
When to call an auto electrician
Book a professional for warning lights that keep coming back, faults that come and go, anything involving airbags or high-voltage parts, and new circuits such as dual battery systems, brake controllers or extra lighting on a 4WD or caravan. Find one in the Darwin directory.
