Frequently Asked Questions
Does the brand of alternator matter?
Absolutely! There is a big difference. Your alternator is an important component of your vehicle and the only way to ensure it will run smoothly, reliably and safely is to purchase quality parts.
What is considered a good alternator?
Output voltage should be around 14 volts (13.8 to 14.5 depending upon the application) with the engine running. If you check the voltage at the battery under the same parameters, you should not have more than a half volt drop between your result at the alternator and the result at the battery.
What shortens the life of alternator?
Overloading, often caused by numerous aftermarket accessories, can greatly shorten the alternator's lifespan by increasing the electrical load beyond its design capabilities. Moreover, battery maintenance can't be overlooked. A failing battery forces the alternator to work harder to maintain power, accelerating wear.
Are aftermarket alternators OK?
Why cheap alternators are the wrong choice. Aftermarket alternators are sold as less expensive OEM replacements, but they aren't always good replacements because they are not identical to the OEM unit. Buyers are often unable to spot the differences in quality, unless they inform themselves.
Are OEM alternators worth it?
But when you consider that an OEM alternator may cost $50 more than an aftermarket alternator, the OEM pays for itself in 1 year with fuel savings, and lots more over the next several years of use.
