I also show you some upgrading options that can be easily added for more convenience and enjoyment. There are some differences, though, not based on quality but by application. I am not a purist by any stretch, but the clash of design eras just comes off as clunky, unintegrated, and anachronistic. Headlamps have prongs that fit into their sockets, while most of the rest of the bulbs use barrel-type sockets. Photo Courtesy Scott Tiemann A wiring harness is a wearable item, and after more than 40 years, it may be simply worn out. As you know, points are wearable items, and over time the gap needs to be maintained for maximum performance. After 40 years or more, ground straps are often frayed, corroded, or even broken.
This Pertro¬nix coil is designed for compatibil¬ity with its module and provides lower resistance. While it certainly is not the cause of all electrical problems, more often than not, a faulty ground is the main source of trouble, especially in a car of this age. This book contains the wiring diagrams for all American cars from 57-65. Ignition The ignition system actually gives you a lot of warning that things are amiss. The idea is to scan manuals for old, vintage or antique American vehicles and their components and make them available on the web, for free.
Are all of the lights working, including the license plate lamp, the reverse lamps, and the interior lighting? Replacement knobs and face-plate decals are available from most restoration parts suppliers and fishing line can be used to repair the loss of movement on the station indicator. A stock alternator is hard-pressed to keep up. These provide a path for the electricity to flow between the body and the frame and therefore allow the circuit to be com¬pleted. The upside is that you can design a custom system for your exact needs and save some money by finishing it yourself. We think that this kind of information should be freely available, as a public resource for the preservation of our industrial history. They add to the efficiency and intensity of the spark, making the most of your new, low-resistance plug wires and fresh spark plugs. Since there are still a lot of Pontiacs from this era on the road, finding replacement starters, solenoids, and accessories is pretty easy.
Ignition switches can also be problematic, and dash-mounted switches can become especially loose. Why are we doing this? Use a multi-tester to make sure that all the wiring is still func¬tional and replace the wiring that does not complete a circuit. If it is not operating properly, the alternator cannot properly charge the battery, prevent¬ing long-term operation. I hate to see a late-model aftermarket stereo in the dash of a classic muscle car because it just looks so incorrect. Spark plugs wear over time as well and should be replaced, taking the time to read the old ones for signs of engine condition and possible problems. These batteries cost less and work better than the originals ever did.
It is likely that a rebuilder in your area can handle the job. Installation can be accomplished using the same procedures as for a factory-original harness. Use a multi-tester to measure the voltage and resistance and then compare them to the actual specs. What about the cigar lighter? He said that it was right in the stock location. Vintage radios can be restored at home if you have the skills or by a number of companies such as Antique Radio Doctor. But really - one of the hardest parts of restoring or servicing old machines is getting decent technical information.
Lectric Limited has become a great source not only of harnesses, but also of correct switches, ground straps, connectors, bulbs, and other items that help get your electrical system back to its original operational condition. Plug the terminal back in and attach the ground wire at the back of the alternator. Conversion kits are available from several sources to upgrade your system to maintain those elevated requirements. Recent advancements in plug wire technology bring new levels of performance with a new generation of low-resistance wires that still look like factory items.

In that amount of time, wiring may deteriorate, grounds may fail, or perhaps some past owner tried to install aftermarket gauges and needlessly started hacking away at wires, causing shorts and other problems.
Is the element burned out or is the socket not working? Often, the terminals have been overtight¬ened and distorted. A wiring diagram from your shop manual lists the number of grounding points and their locations. Ground straps are particularly important on a full-frame car, as they provide a path between the body and frame where electricity can flow. Clean the terminals of all corrosion and make sure they are making proper contact with the bulbs at their particular connection points. We are some guys who like old iron. This unit, manufactured by Pertronix, replaces the breaker points, so the spark consistency is stronger and more precise.
Manufactured by Antique Auto Radio, this head unit fits in the stock location but is only about 3 inches deep, taking up less space than a stock radio. Unless you are competing in concours judging, pass on 6-gauge battery cables and reproduction tar-top batteries. Perhaps a plastic wire insulator cracked with age and exposed a bare wire to some bare metal and a short was caused. With the body isolated from the frame with rubber body mounts, interior electrics really have no way to complete a circuit without them. Use a flat-head screwdriver to push against the belt. This gives you the opportunity to isolate each trouble spot and figure out where the most logical failure point is. The system includes comprehensive instructions, which can be downloaded from the web¬site.
