Resolve starting and charging faults. We test battery health, rebuild charging circuits, troubleshoot wiring harness failures, and diagnose parasitic draws in Missoula, MT.
Warning Signs of Electrical Problems
If your vehicle exhibits any of these warning signs, get in touch with our Missoula shop before minor symptoms develop into severe mechanical failures.
Slow Engine Cranking
If your engine cranks slowly or just clicks when you turn the key—especially after your vehicle sat parked at Washington-Grizzly Stadium during a cold Griz football game—your battery charge is low or your starter is weak.
Charging Light Active
A battery symbol or ALT warning light on your dash means your alternator is not producing enough voltage to charge the battery while running.
Dimming Headlights
If your headlights or interior dashboard lights dim when your engine drops to an idle, your alternator's internal voltage regulator is failing.
Recurring Blown Fuses
If a specific fuse keeps popping shortly after you replace it, you have a short circuit where a bare wire is touching metal or a component is overloaded.
Our Electrical & Charging Services
Our mechanics follow factory service procedures, using professional diagnostic tools and premium replacement parts to make sure your repair is done right.
Alternator & Starter Repair
Your alternator charges the battery while the engine runs, and the starter cranks the engine to turn it on. We test alternator output voltage under load and measure starter motor current draw. We then replace failing units with premium components to ensure your engine starts reliably and accessories get steady power.
Wiring Diagnostics
Electrical shorts or bad grounds can cause gauges to flicker, lights to fail, or fuses to blow. We use digital meters and factory wiring diagrams to trace circuit paths under the hood and dashboard. This helps us locate pinched wires, find short circuits, and repair damaged wiring harnesses without replacing the entire system.
Battery Testing & Replacement
Sub-zero winter cold snaps in the Bitterroot Valley drain battery capacity quickly, leaving you stranded. We run load tests on your battery to measure its true Cold Cranking Amps (CCA), swap out weak batteries for high-quality replacements, clean the terminal connections, and apply protective spray to prevent battery acid corrosion.
