Truck Electrical Repair & Diagnostics in Edmonton

Electrical troubleshooting for trucks and trailers in Edmonton: no-starts, charging problems, wiring faults and computer diagnostics.

Electrical problems are hard to find because the symptom often shows up far from the cause. A corroded ground can look like a failing starter, and a chafed wire can set codes in three different systems.

Reading codes, running tests and changing parameters on a modern truck takes diagnostic software, either the engine maker's own (such as Cummins INSITE or Detroit DiagnosticLink) or a multi-brand tool. Tell the shop the truck's make and engine when you call, so it can confirm it has the right software.

Trailer lighting faults usually start at the 7-way plug or the main harness; see semi trailer repair. A no-start that isn't electrical is covered under diesel engine repair.

Common jobs

• No-start and hard-start diagnosis

Have this ready when you call

• Year, make and model of the truck or trailer, and the unit number if it's a fleet unit
• Where the unit is now, and whether it can be driven safely
• Any warning lights or fault codes on the dash
• When the problem started and what it's doing (noise, smoke, power loss, air leak)
• A PO number, if your company uses them
