Dodge Ballast Resistor Wiring

Over time the ballast resistor can be damaged by normal wear and tear so there are a few things to look for when you suspect a bad or failing ballast resistor needs servicing.

Dodge ballast resistor wiring. During cranking the ballast resistor allows normal battery voltage into the coil to ensure a good strong spark for starting the engine. However this item may be purchased online to be shipped to home or may be purchased in person by visiting a napa store. The ballast resistor is commonly found in older vehicles because they did not have the benefit of circuit boards found in most of today s vehicles. Avoid the exhaust manifolds and sharp edges follow existing wiring harnesses if possible.

We apologize that this item is not available for pickup in store at this time. In simple terms the ballast resistor in a mopar limits the amperage or current flow through the coil while the engine is running thereby extending the life of the coil and breaker points of the. Pickup in store not currently available. Do not reconnect the wires.

Remove the old ballast resistor and install the new ballast resistor in its place. So if you have the ballast resistor in series with the ign coil as they should be connected when the coil starts to charge circuit current starts low. The ballast resistor is subjected to significant amounts of heat during operation the resistor s resistance level increases or decreases with the application of heat and voltage. The distributor does not contain breaker points or a condenser these parts being replaced by a distributor re luctor and a pick up unit.

Yes but like terry just explained there is no way to get a total amperage draw of 3amps with a 1 79ohm coil and 6ohm resistor. Ballast resistor resistance 70 80 deg f there is only 1 possible ballast resistor listed. Route the blue wire to the ballast resistor. Disconnect the wires from both ends of the original ballast resistor.

A ballast resistor changes it s resistance to control current flow. I would like a 5 pin dodge chrysler ignition ecu box from a 1975 pickup truck example dodge w 100 with 318 v8 and the 4 pin ballast resistor that goes with it. The ballast resistor instructions say to mount the leads across the two outside leads of the 3057 3157 sockets just to make sure i spliced into each of the three wires and took some voltage measurements and with the webelectric kit the wiring is the same so use the two outside wires on the socket to connect to the resistors.
