Alternator, Starter & Car Battery Replacement Services
Alternators
Your alternator powers essential systems while your engine is running. If your lights dim or your battery drains unexpectedly, it may be time for alternator repair or replacement. Our expert team will test your alternator and get you back on the road safely.
Batteries
Your car battery powers everything from the ignition to headlights. If you're jump-starting regularly or seeing a dashboard warning light, it's time to consider a car battery replacement. Our team offers fast battery testing, replacement, charging, and recycling services in Pocatello. Not sure how often to replace a car battery? Most drivers should check their battery after 3 years and consider replacing by year 5-especially in extreme climates or with frequent short trips.
Starters
The starter gets your engine going. Clicking sounds or a failure to start can signal a faulty starter motor. We'll diagnose starter issues and repair or replace the component as needed to ensure reliable starts every time.
Car Starting FAQs
What sound does a bad starter make?
A failing starter often clicks when you turn the key-but it might also produce a grinding or whirring sound, or no sound at all. If your engine won't turn over, schedule a diagnostic with Master Mechanix to determine if starter replacement is needed.
How do I unlock the steering wheel if it's stuck?
Apply pressure to the brake and turn the steering wheel slightly while turning the ignition key. This typically releases tension in the steering column and unlocks the wheel. If it doesn't work or the battery is dead, contact a professional to avoid damaging the ignition system.
Battery FAQs
What should I avoid when replacing a car battery?
When replacing a car battery, avoid letting tools bridge the terminals-it can cause sparks or electrical shorts. Make sure the battery is properly secured before connecting cables. Unsure how to replace a car battery safely? Our team is here to help with expert, affordable installation services.
What's the most common mistake when jumping a car?
The #1 mistake is connecting the jumper cables incorrectly-reversing the positive (red) and negative (black) leads can cause serious damage to your alternator or battery. Always double-check your connections and avoid using damaged or low-quality cables. If you're unsure, it's safest to let Master Mechanix handle the jump-start for you.

What People Say About Us
I looked at the reviews online and decided to give Master Mechanix a try and was not disappointed. They fixed my truck in like a quarter of the time I was expecting and at a incredibly reasonable price. Ever since I have been driving I have never had good experiences with mechanics, but this is the exception. They were very nice and did not try and sell me a bunch of stuff I did not need. Next time any of my vehicles has a problem I know where I will be going.
I had my vehicle towed here for repairs after a breakdown on the freeway a few weeks ago and, although they were a little backed up due to bad weather, they figured the problem out quickly and let me know exactly what to expect in cost. The part that was broken was still under warranty by the manufacturer, so Master Mechanix took care of the work and warranty reimbursement with me only having to pay for the initial diagnosis! Very happy with how everything went and would recommend these guys to anyone. Thanks!
Best general mechanic I've ever been to. I've always gone to the dealership where I've got my car because they are they only ones I trust even though they are very expensive. I came here because the dealership said they didn't have the parts to do the job and recommended Master Mechanix. Very fast and cheap. very happy with the service and will go back in the future.
Ray is an excellent technician! High quality work and very honest! I have been going to Master Mechanix for years.
I have brought several of my vehicles in to Master Mechanix for troubleshooting and repair over the last 15 years I have lived in the Pocatello area. Their pricing is very reasonable, the repairs are quick and I have never been disappointed or unsatisfied with the service. Their work is always top notch! Ray always takes the time to explain options, pricing and repair time and doesn't ever attempt to "pile on" a bunch of other work. I continuously recommend Master Mechanix to family and friends.
They provided great service and great education about how to properly care for my car. Thanks guys!!
