Auto electrical repair in Brampton you can trust.
Sultan Motors handles batteries, alternators, starters, wiring faults, sensor failures, and full electrical diagnostics for every vehicle in Brampton.
Electrical faults are our specialty, not a guessing game.
Modern vehicles run on dozens of computers, hundreds of sensors, and kilometres of wiring. Sultan Motors uses meters, oscilloscopes, and manufacturer wiring diagrams to trace faults to the wire, not just the module, so repairs are surgical instead of expensive.

Electrical diagnosis done properly.
- 01
Wiring diagrams
We use factory wiring diagrams to test at the exact pin, not swap parts hoping to get lucky.
- 02
Real testing equipment
Meters, scan tools, and scopes let us watch signals live and prove the fault.
- 03
Root cause fixes
We fix the underlying cause of shorts and drains so the problem stays fixed.
Signs of an electrical fault.
Electrical faults tend to start small and intermittent. Testing early is quicker and cheaper than chasing a fault that has spread.
- 01
Slow cranking or a dead battery
A starter that turns slowly, especially on cold mornings, or a battery that keeps needing a boost usually means a weak battery, a charging fault or a drain. A load test tells you which.
- 02
Dim or flickering lights
Headlights that dim at idle and brighten with revs, or dash lights that flicker, usually point to a failing alternator or a poor ground connection.
- 03
Warning lights that come and go
ABS, airbag or traction control lights that appear and clear on their own often trace back to a sensor, a connector or a chafed wire rather than the module itself.
- 04
Accessories that stop working
Power windows, locks or the radio failing one at a time can be a fuse, a relay or a wiring fault. We trace the circuit on factory diagrams instead of swapping parts until one works.

Questions Brampton drivers ask.
Usually one of three causes: an aging battery, a failing alternator, or a parasitic drain from a stuck circuit. Sultan Motors tests all three so you replace the right thing once.
Yes. Rodent damage is common in Brampton winters. We locate every damaged section and repair or replace the harness with proper connectors and heat shrink.
It depends on the vehicle and part quality. Sultan Motors provides a written estimate after testing so you know the price up front.
Most last three to five years. Cold weather cuts cranking power and summer heat shortens battery life, so a battery that tests weak in the fall is worth replacing before the first cold snap.
It is a circuit that keeps drawing power after the car is switched off, such as a stuck relay, a module that will not go to sleep or an aftermarket accessory. We measure the draw and isolate the circuit fuse by fuse.
Yes. An alternator that undercharges leaves the battery permanently low, and one that overcharges can cook it. That is why we test the charging system whenever a battery fails early.
