When this service may help
- No crank or intermittent start
- Battery not charging
- Lighting or trailer socket fault
- Blown fuse or damaged wiring
Describe when it happens
Intermittent faults are easier to trace when you record weather, vibration, accessory use and dashboard behaviour. Do not repeatedly replace a fuse that continues to fail.
Protect connected systems
Incorrect jump-starting or testing can damage control modules. Follow the vehicle manufacturer's procedure and use a qualified commercial-vehicle technician.

Frequently asked questions
Can a mobile auto electrician repair trailer lights?
Many can, but confirm trailer electrical experience and the socket or system type when requesting help.
Is a flat battery always a battery fault?
No. Charging, isolator, starter, wiring or parasitic-drain faults can produce similar symptoms.
