Mobile Alternator Repair in Salt Lake City, UT
The battery light comes on and the headlights go dim at idle. A few miles later the car quits in traffic. Most of the time that is the alternator and not the battery. We test the charging system where the car sits, and if the alternator is the failed part we replace it there.

More Details
An alternator rarely quits all at once. It usually drops output first, so the battery carries the load and goes flat a day or two later. That is why a jump start gets you moving and then the car stops again. When it happens here, the address system works in your favor: the grid counts blocks out from Temple Square, where Main Street, State Street and South Temple meet, so you can give us a location like 1300 East and 2100 South without knowing the name of the road you are on. The blocks are long, and that cuts both ways. Walking one of them for help is a real walk, and pushing a dead car out of a travel lane is worse. Stay with the car and give us the two numbers, and we bring the parts and the test meter to you.

Frequently Asked Questions About Alternator Repair in Salt Lake City
Is it the battery or the alternator? +
A battery that takes a jump and then dies again within a day usually points at the alternator. We check output at the alternator and voltage at the battery, so you know which part failed before you buy either one.
Can you replace an alternator on the side of the road? +
Usually yes, as long as the car is out of a travel lane and there is room to work. Some engines bury the alternator behind the belt drive or an axle, and those are better done in a driveway or a nearby lot.
How long does the job take? +
Most alternators come out and go back in inside two hours once we have the part on hand. Testing first adds a few minutes. A bad ground or a worn belt can look exactly like a dead alternator, so we rule those out before pulling anything.
Will I need a new battery too? +
Sometimes. A battery that has been run flat repeatedly by a failing alternator often will not hold a charge afterward. We load test it while we are there and tell you either way.
