Starter Replacement Parts
JEGS 10038 R Terminal Diode Harness Kit is for use with GM vehicles originally equipped with breaker point ignition and ballast resistor. The wiring harnesses "R" circuit diode is a ballast resistor bypass. This terminal is "no connection" when the starter is at rest and provides +12VDC to the ignition coil during cranking for easier engine starting. Cars that do not have a ballast resistor (ie: HEI, MSD or other aftermarket ignition systems) should not need this connection. In most cases this wire will be eliminated, however, cars equipped with a ballast resistor (ie: Breaker Point or Mallory Unilite) may need this harness if the engine has no ignition during cranking, then the wiring of the coil is going to require an "R" terminal signal.

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
