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 Idaho Falls. 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 FAQs
What are common mistakes when jumping a car?
The most common error is reversing the jumper cables-always connect red to positive and black to negative. Using low-quality cables, letting clips touch, or jumping a battery with visible damage can cause serious electrical damage. When in doubt, have All Things Automotive & Diesel Service perform the jump safely.
What should I be careful of when replacing a car battery?
When replacing a car battery, avoid touching both terminals with the same tool-it can cause a short. Don't drop the battery or reconnect cables before it's securely in place. If you're unsure, let our technicians handle your car battery replacement professionally.
Car Starting FAQs
How do I unlock a locked steering wheel?
Press the brake and gently turn the wheel in the direction it moves slightly while turning the key. This relieves pressure in the column and allows the wheel to unlock. Never force it-if the battery is dead or the key won't turn, consult a professional technician.
What does a failing starter sound like?
Common sounds include a single click, grinding, or even silence when turning the key. These signs often indicate a starter issue that requires immediate inspection and service.
