One wire alternators are a popular choice for building hot rods or project vehicles. Ease of installation, wide availability, and reduced cost are just a few of the reasons builders love single wire alternators.
One wire alternators work by only utilizing a single wire connected directly to the positive post on the battery. The “ground” is achieved through the alternator’s physical connection to the engine block, and therefore requires a high-quality ground strap between the engine block and vehicle chassis. However, because there is only 1 wire to install, it is much easier to route and access that wire during installation...
One wire alternators are a popular choice for building hot rods or project vehicles. Ease of installation, wide availability, and reduced cost are just a few of the reasons builders love single wire alternators.
One wire alternators work by only utilizing a single wire connected directly to the positive post on the battery. The “ground” is achieved through the alternator’s physical connection to the engine block, and therefore requires a high-quality ground strap between the engine block and vehicle chassis. However, because there is only 1 wire to install, it is much easier to route and access that wire during installation or replacement. This makes servicing and repairs much easier and can help keep your vehicle’s engine bay tidier and more attractive.
As long as you select an alternator that produces enough amperage to meet the demands of your vehicle’s electrical system, a one-wire alternator should be capable of providing years of service. But in the event that one should fail, because single wire alternators are simple, troubleshooting and down time are kept to a minimum.
Although they are commonly referred to as GM one wire alternators, there are options available for Mopar and Ford, as well. Summit Racing Equipment offers a wide variety of one wire alternators from trusted brands: no copycats, knockoffs, or third-party sellers here! Use the powerful Make/Model search tool to find the one wire alternator that’s perfect for your ride or project.
