How to choose the best high amp alternator products

First, you need to know how to look for the best product. In that way, you can get the most out of it once installed in your vehicle. Here are the following factors that you should consider in choosing an HO alternator.

Know exactly what you need

In order to narrow down the options that you have, you need to know exactly what you need. The high output alternator varies on the model of vehicle that you have. Therefore, you should make sure that you limit your search to available products specified for your model of vehicle.

As much as possible, you should not exceed the amperage that your vehicle can handle otherwise you will encounter serious problems down the road. Most of the factory high output alternator that you can find ranges from 60-100 amp only. Just enough to handle all the necessary accessories of your car.

Know when to upgrade your high amp alternator products

Upgrading your high output alternator isn’t as easy as changing your car’s air filter. You need to make sure that your vehicle really needs the upgrade. If you have no idea when to upgrade your HO alternator, you should take a look at your voltmeter. It would help you determine if you need to change it or not.

Tips for getting the most out of your alternator

Now that you have chosen the best HO alternator for you, you should know how to get the best out of it by practicing the following.

Use the proper wire

One of the high amp alternator products that you should pay extra attention to is the gauge wire that you are going to use. The wire will let the power from the alternator flow to the battery and to the electrical system. If you choose a gauge wire that is too small, it will most likely restrict the electricity flow and will affect the overall performance. You can use various charts as your guideline in choosing the most appropriate gauge wire for your vehicle and electrical system.

High amp alternator products should be in great condition

High amp alternator products such as tensioner and belt alternator should be all in good condition. High amp alternators have smaller pulley than stock so that it can overdrive the system for up to 16%. Therefore, even the slightest load will add too much stress to your belt, so make sure that it’s always in great condition.

Balance the power of your alternator

You should also know how to properly balance the power in your alternator. If you want to get the most out of it and ensure that it will work accordingly, you have to make sure that the power is balanced. In that way, it will be easier for you to create horsepower gain.
