All-out charging system meltdown is an all too common failure to see on old cars. While charging systems back then were minimalistic, more modern alternators pack a juicier jolt and can do big damage if not properly installed. Chances are, if you have a stock charging system, then stock-style wiring is probably just fine. Alas, muscle car mechanics are like moths to a flame when it comes to an easy upgrade and an alternator usually fits the bill. Unfortunately, the wiring doesn’t always get the same care.

Powermaster can help with both knowledgeable insight and bolt-on products to make sure your alternator upgrade is complete, safe, and made to last. “Size is important when it comes to charge wires because an undersized charge wire is the number one install issue on our tech line,” the catalog states. Their wire gauge capacity chart provides a quick reference to how big a charging wire needs to be given the alternator’s output and the length of the wire.

Once you know what you need, take a gander at their factory-assembled cables that come with terminals, lugs, and boot professionally installed. A variety of gauges and lengths are available to fit a plethora of applications. After you’re confident on the plus side, keep in mind that a good alternator ground is just as important. If you don’t think the case is getting a good enough ground through it’s bracketry, a dedicated ground cable or strap may be necessary.
