Understanding the various components in an electrical system and how to safely and efficiently make them all work together is key to resolving electrical problems or installing new circuits. We’ll take an up-close look at automotive electrical systems.
Whenever planning any electrical project safety should be your primary concern. From wire size to fuses to wire routing there are several considerations that should be made. We’ll examine some good practices and important tips to planning out your project.
There’s a right tool for every job and electrical projects are no exception. In this session we’ll look at the tools commonly used when servicing electrical circuits. We will examine Crimpers, Wire Strippers, Multi-meters, Lug Crimpers, Test Lights, Soldering Irons and so much more...
The battery is at the heart of any electrical system, and although often overlooked it serves many important functions. From initial start to providing reserve power to serving as a system buffer, the batteries role is vital to the health of the system. We’ll also review the different types of batteries available for classic cars and how to properly maintain them.
It’s no secret many electrical problems can be traced back to bad or improper grounds. In this session we look at the importance of properly sized and connected ground wires and cables.
There are several different types and sizes of electrical wire, and knowing which choices to make will ensure your system operates efficiently and safely. By understanding the carrying capacity of your wire and the amperage load of various components you’ll be able to make sound decisions.
There is no shortage of different types of electrical connectors that can be used on your classic car. In this session we’ll examine some common electrical connectors and how to properly crimp them onto the wire, as well as a few tricks to make modern connectors look at home in any classic car. We’ll also look creating multi-wire connectors and how to crimp-on those types of terminals as well.
Nothing is probably more reliable than a properly soldered electrical connection, but using the right products and processes will ensure your connections are safe and will last forever. We review different types of solder and soldering flux and how to use them properly.
A fuse is like an insurance policy, most of the time you don’t need them but when you do you’re glad they’re there, and if you don’t have them the results can be disastrous. Fuse panels however didn’t commonly appear in cars until the late 50s, as cars were often protected with only a few circuit breakers for the entire car. In this session we’ll also take a look at how different circuits should be protected and discuss adding additional fused circuits to classic cars.
When planning your electrical system, relays are an important component in delivering power to high draw components without the need to run large gauge wire over great lengths or needing to use high-amperage switches. We take a close look at how relays operate, how they are wired and when to use them.
Master Disconnect Switches or Kill Switches are a must have addition to any classic car. These handy little devices ensure your battery doesn’t drain when not in use, eliminates the risk of an electrical fire and can act as a theft deterrent. We examine how they work and how to keep items like clocks and radio presets working even with the switch turned off.
Keeping your wiring organized and protected is especially important in the engine compartment, where there are moving and hot component as well as dirt, moisture, grease, oil and other potential hazards. Using wire looms is a proven way to keep your wiring organized and protected. With the many types available it’s important to select a loom that fits the style or era of your car.
Most cars are equipped with either a voltmeter or an ammeter, but both can give you important information about how well your electrical system is functioning. We take a look at the information each of these gauges provides and the type of feedback we get from them.
The ignition circuit is one of the primary circuits in an automobiles electrical system. It is how power is delivered to the spark plugs to ignite the fuel for combustion. We take an in-depth look at the various components in the system and how they all operate together.
The charging circuit is vital to ensuring the car maintains sufficient power to operate the automobile while recharging the battery. The charging circuit is a relatively simple circuit and includes: alternator/generator, voltage regulator, volt/amp meter, and battery. In this session we’ll look at how all of these components work together.
Lighting circuits are typically one of five lighting sub-systems, these are: Interior, Parking/Taillights, Headlights, Instruments and Directional Indicators. In this session we will discuss how these important lighting systems work.

An Automotive Electrical System can seem like black magic to most of us, especially when things go wrong.

But in practice, most electric circuits are relatively simple and most problems can be isolated with a series of tests. Additionally many classic car enthusiasts also want to add modern electrical equipment to their vintage rides, but understanding the limits of vintage electrical systems is key to making everything work and may require other upgrades too.

Wiring new circuits or resolving electrical problems starts with fully understanding the various components in an automotive electrical system and how they all work together.

Mark Simpson

Like many of us, Mark’s passion for cars started in his early teens. He first dreamed of owning a ’34 Ford 3-window coupe. But as a wide-eyed 15-year-old, he spied a ’40 Chevrolet Coupe alongside a garage while walking home from school, which he picked up for $150. After being told by his father that the new heap would not have a place in the home garage or driveway, Mark finagled his way into a local auto body garage, doing some grunt work around the place after school. At that moment, the spark for old cars became an unquenchable flame. Using mostly money he made painting cars for local dirt track racers, Mark rebuilt that ’40 Chevy, but had to sell the car to help pay for college. Although the car was gone, the passion for restoring old cars remains to this day. After college, Mark’s passion continued with the purchase of a ‘31 DeSoto, a ‘37 Chevrolet Coupe, a ‘69 Camaro, a ‘54 Ford F100 and countless other cars over the years. Currently, Mark’s collection includes numerous street rods, customs and muscle cars. But the old car passion is fueled by more than just building and owning cars. In addition to serving as executive director of the National Street Machine Club and editor of Street Thunder magazine between 2005 and 2011, Mark has served as an active member in numerous local, regional, and national car clubs. This lifelong passion for old cars allowed Mark to realize his dreams of introductions and building relationships with industry icons, and he’s had the opportunity to work with many of the top hot rod and restoration shops in the Midwest, giving him a first-hand inside look at the tips and tricks the pros use to build world-class cars. Mark has extended the passion to his family members, with his wife and children deeply hooked. His daughter rebuilt her first engine at the age of 16, and has worked in the automotive aftermarket business since she was 17. She is currently a regional sales rep for a national motor parts company, while his son attended college at WyoTech and has worked for some of the top Hot Rod shops in the country. He is considered by many as a master sheet metal fabricator and is equally gifted in his custom automotive upholstery skills.
