Service / Charging system
Alternator repair before it strands you twice.
If your battery keeps dying, the alternator is a prime suspect. We test the whole charging system at your location and replace the alternator and belt on-site when that is the fix.

Signs you need it
- Battery or charging warning light
- Headlights and dash dim or flicker

Honest limits
- On some engines the alternator sits deep under other components. Those jobs take longer, and a few are better handled with a lift. Your estimate reflects this.
- If testing shows the alternator is fine, we look for the actual drain instead of swapping parts.

Questions drivers ask
Can I drive with a bad alternator?
Only briefly. The car runs on battery power until it is drained, and it can shut off while driving. If the battery light comes on, head somewhere safe and call.
Will a jump start fix a bad alternator?
A jump may get the car running, but a failing alternator will not recharge the battery, so you will likely be stranded again soon.
Do you replace starters too?
Yes. Starters and alternators are part of the same starting and charging system and are both common mobile repairs. Mention symptoms when you request a quote.
