Smog Mart Inc, Smog and Automobile Repair Center
No-start? We find out which part it is.

Starter, alternator and battery repair in Sacramento.

Click but no crank, a battery light, headlights dimming at idle: starting and charging problems look alike but have different fixes. We test the battery, the starter and the alternator so you replace the part that's actually failing, and the diagnostic fee comes off the repair if we do the work.

Which one is it?

What the symptom usually means

  1. One click, no crank

    Usually the starter or a bad connection. Sometimes a battery with a dead cell that still reads charged.

  2. Rapid clicking, slow crank

    Usually a weak battery, or an alternator that isn't recharging it. A jump that works and then dies again points at the alternator.

  3. Battery light on while driving

    Alternator, belt or tensioner. Get it checked soon; when it stops charging, the car stops.

What we test and repair

Why we test before we replace

Starters, alternators and batteries fail in ways that imitate each other, and the wrong part is an expensive guess. We load-test the battery, check what the alternator is putting out at idle and under load, check the belt and tensioner, and check the starter draw and its connections. Then you get the findings, and if you want the repair done here we prepare an estimate from them.

A no-start with a check engine light or other warning lights on can be a sensor or wiring issue rather than the starter. That’s a job for a full diagnostic.

Common questions

Starter questions

How do I know if it's the battery or the alternator?

A dead battery that jump-starts fine and then dies again usually means the alternator isn't charging it. We test all three, battery, starter and alternator, before recommending anything.

How much will it cost?

The diagnostic is $175, credited toward the repair if we do the work. Parts vary by vehicle, so we show you the findings and prepare an estimate before anything is replaced.

My car won't start. How do I get it to you?

Give us a call. We work with trusted towing partners and can help you arrange service to the shop.

Can I bring my own starter or alternator?

No. We supply the parts we install so we can verify fit, quality and the repair we're standing behind.
