Common Issues
Electrical Problems We See Every Week
Most "electrical gremlins" are corroded grounds, chafed wires, or a dying battery. We find the small thing that's actually wrong.
Dead Batteries Overnight
Truck dies after sitting. Usually a parasitic draw — a stuck relay, bad accessory, or charging fault. We trace the actual amperage drain.
Charging Light On
Voltage dropping, batteries cooking, or charging light flickering. Alternator, regulator, belt, or wiring — we identify which.
Trailer Lights Out
A dead tail or marker light is an automatic ticket. Usually the pigtail, ground, or a chafed wire in the harness.
ABS Light Won't Clear
Tractor or trailer ABS fault. We scan the system, trace the wheel sensor, modulator, or wiring fault, and repair the actual cause.
Random Warning Lights
Check engine, ABS, ATC, brake — flickering on and off. Usually a connector, ground, or sensor — and rarely the expensive thing.
Our Process
Test First. Then Fix.
Four steps from "won't start" to back on the road.
-
01
Test
Multimeter, scanner, load tester — we measure what's actually happening before we open the parts catalogue.
-
02
Quote
Clear estimate with parts, labour, and timeline. We tell you what's the cause and what's just a symptom.
-
03
Repair
Proper splices, sealed connectors, factory wiring colors and routing. Nothing held together with electrical tape.
-
04
Verify
Re-scan, re-test, and confirm no codes come back. Light check on every position before you roll out.

FAQ
Electrical & Lighting — Quick Answers
My truck cranks slow — is it the batteries or the starter?
That's exactly what the test tells us. A lot of "bad starter" calls turn out to be tired batteries or corroded cables. We load-test the batteries, check the cable drop, and test the starter under load before recommending a replacement.
Can you find a wiring short or chafe?
Yes. Tracing shorts, chafes, and parasitic draws is bread-and-butter work for us — we use a multimeter, current clamp, and good lighting to find the actual issue, not just splice over it.
Will you fix the ABS light?
Yes — we scan the tractor and trailer ABS modules, trace the fault to a sensor, modulator, or wiring issue, and repair the cause. An ABS fault is an automatic safety failure, so it's worth fixing properly.
Can you install extra lights, strobes, or a reverse alarm?
Yes — we install auxiliary lighting, work lights, strobes, beacons, and reverse alarms with proper wiring, fused circuits, and switches you can actually use.
How long do electrical jobs usually take?
A bad bulb is minutes. A short or parasitic draw takes time — we don't bill you for guessing, we bill you for the time it takes to actually find it. You'll get an estimate before we start.
