Battery, Starter, & Alternator Repair
Expert battery, starter, and alternator repair in St Paul, MN. Complete electrical system diagnostics and repair for reliable starting and charging.
A car that won't start always picks the worst moment. Usually it's the battery, the starter, or the alternator — and they're easy to confuse. Roy's Service tests the whole charging system so you replace the part that's actually bad, not the one you guessed. St Paul drivers count on us to get them started and keep them running. Call (651) 776-9494 or book online.
Signs of a battery or charging problem
- Slow or no crank when you turn the key
- Clicking but no start
- Dim or flickering lights
- Dash battery or charging warning light
- Needing a jump-start more than once
- Electrical accessories acting up
We test before we replace
A dead car can be three different problems. We test the battery, starter, and alternator together so you don't pay to replace a good part.
- Battery load and state-of-charge test
- Starter draw and operation test
- Alternator output and charging-system test
- Check cables, grounds, and connections
What we repair
- Battery replacement and terminal/cable repair
- Starter replacement
- Alternator replacement
- Charging-system wiring and connections
- Parasitic-draw diagnosis (the battery that keeps dying)
Why the right test matters
Swapping a battery won't help if the alternator isn't charging — you'll just be stranded again next week. Testing the whole system the first time saves you a second trip and a second bill.
All makes and models
Domestic, Asian, and European vehicles, with quality, vehicle-rated parts.
Honest, upfront pricing
- We test and tell you which part is actually bad
- A real price before any work begins
- No replacing good parts to be safe
