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 Mesa. 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.


Battery Related FAQs


What can go wrong when jumping a car?

Incorrect jumper cable placement-reversing polarity-is a leading cause of alternator or battery damage. Use red for positive and black for negative, and never let the clamps touch. Damaged cables or corroded battery terminals can also pose a risk. For peace of mind, let Moncur's Automotive perform the jump safely.

What precautions should I take when replacing a car battery?

Use insulated tools and avoid shorting the terminals. Handle the battery carefully to prevent drops or tipping, and always secure it before reconnecting the cables. If you're not familiar with replacing a car battery, let our trained team handle it with precision and care.

Car Starting Related FAQs


How do I release a locked steering wheel?

Place your foot on the brake and turn the wheel in the direction in which it has a little range of motion. This should ease the tension in the steering column and allow you to turn the key. Turning the key unlocks the steering wheel. Do not try to unlock your steering wheel without a key or if the battery is dead. This should only be done by a professional auto repair technician.

What are the warning signs of a bad starter?

A failing starter may click when you turn the key or produce a slow whine. In some cases, there may be no sound at all. If your car won't start and the battery is healthy, it's likely time to inspect or replace the starter motor.

What Our Customers Are Saying

Kerry was professional, polite and knowledgeable. He explained everything clearly and thoroughly. I appreciate his care and patience with me as a new customer. I trust that he has the expertise to diagnose items others miss, while not upselling you for repairs or parts that you do not need. I appreciate his ability to use his experience in solving intermittent, or tricky issues. I would not hesitate to bring my cars to his location again or to recommend friends and family to his shop. Everything was straightforward and handled with courtesy. I look forward to working with Moncur's in the future.

Moncur's was great! A/C went out on my car so I decided to take it to AAA to get diagnosed. They told me since the leak was so small that in order to find it, they wanted to charge me $450 to re-charge my A/C system up with refrigerant & dye, and then come back when the system was empty again so they could find the leak and diagnose what needed to be repaired/replaced. Then they were going to charge me that same price for refrigerant, AGAIN, on top the cost to fix the leak. Seriously? Moncur's found the leak by pressurizing the system overnight with dye and replaced the leaking condenser quickly. Had my car back to me working again within 2 business days and a 2 year parts,service, and labor warrenty. Excellent customer service also. Take you vehicle here to this trusted family business and not AAA. Thank you Moncur's!
