💬 Alternator Service: FAQs

Mechanic and customer discussing alternator replacement options over their vehicle

Have questions about alternator service or repair? Here’s what you need to know to keep your battery charging right.


How long does an alternator repair last & when should I replace it?

An alternator repair should last approximately 100,000 km or longer. At 20,000 km traveled a year, an alternator repair should last 5 – 7 years.

How can I temporarily fix my alternator?

The only option to temporarily fix an alternator is to tap it lightly with a hammer. This will sometimes shake things up and interrupt corrosion of failing internal parts.

How do I check my vehicles alternator?

An alternator is checked using a multi meter. Attaching the multi meters cables to the positive and negative terminals of the battery and checking for a reading of 12+ will indicate if the alternator needs repair or replacement.

Can a bad alternator drain my battery?

The short answer is no. However, electrical components in your vehicle such as the clock and alarm system use battery power in the background while your engine is running or not. Your alternator provides charge to the battery while the vehicle is running. If the alternator is failing to provide this charge, your battery will drain faster as these components are running even while the car is off.

Do I need a new battery after an alternator replacement?

If the battery has drained due to a faulty alternator, it may be possible to recharge the battery to capacity. In cases where the alternator repair was delayed and a continuous drain of the battery has happened, a replacement battery may be necessary. The older the battery at the time of an alternator repair the more likely it will need to be replaced.

Can I jump start my battery with a bad alternator?

Jump starting a vehicle with a bad alternator is possible. However, as mentioned above, the alternator is responsible for charging the battery. So if your battery has drained as a result of a bad alternator, any jump start to your vehicle will be short lived as the alternator is not performing it’s function to charge the battery when the engine is on.
