Getting Grounded

Note: This originally appeared in Volume 2, Number 2 of Street Rod Life Magazine.

Let’s start with the basics. Electrically speaking, ground is a point of commonality and nothing more. Since no automobile that I’ve seen has a rod driven into the ground next to it, where is ground in your car? Ask ten enthusiasts where ground is in their car and they’ll immediately point to the negative battery terminal. Are they correct? No. Let me explain.

High Output Alternators 101

Generally speaking, there are a few things you should be aware of when installing a high output alternator. Installing and wiring it correctly will ensure you get all the performance it’s capable of.

Charging Systems 101

We are often asked, “How do I make my charging system bulletproof?” While there is no single answer, here are the three fundamental areas of focus.

Use Quality Parts, Sized to the Application

Sure, that’s why you’re here. Our site is full of the highest quality parts available and it’s our mission to ensure that you get the performance you’re looking for. It’s always less costly over the long haul to be realistic with yourself about the application and your expectations.

For example, if you’ve added a bunch of accessories to your vehicle which it was not originally equipped, the stock alternator may simply not be large enough. Helping you choose the correct size alternator, cables, etc – it’s what we do. So, you’ve done all that – what then?

The Truth About the Big 3 Upgrade

Wow! There seems to be a ton of misinformation about this topic around. I’ve seen and heard some pretty far-fetched stuff. Keep in mind that all of our Big 3 Upgrade Kits are a direct reflection of our findings in regards to measured performance and our more than thirty years of experience in upgrading vehicle charging systems, not something we read on the Internet.

So, let’s set the story straight.

Battery Disconnects 101

One of the most common questions we field is, “Which battery disconnect do I need?” In order to determine that, you need to know how you intend to use it. There are two main purposes:

Disconnect the battery when storing the vehicle. This convenience allows you to store the vehicle for an extended period of time without worry of the battery running flat due to parasitic draw of the accessories . ECUs, BCMs, PCMs, radios, clocks, etc. all draw a very small amount of current with the vehicle sitting to retain settings or data.
Pass tech at your local track. The NHRA and most other sanctioning bodies mandate a Battery Disconnect Switch that is clearly labeled and externally accessible for any vehicle with a battery that has been relocated to the rear of the vehicle. This affords the safety crew the ability to shut off a running engine and disconnect power to the vehicle’s accessories in the event of a crash, rollover, etc.
