Genuine Parts 41-11500

Genuine Parts 41-11500 is a 1.8-ohm ceramic ignition ballast resistor for classic breaker-point ignition systems using an external coil. It limits primary-coil current while the engine is running.

Application / fitment

The resistor is a restoration part for selected classic General Motors vehicles. Confirm required coil resistance, wiring arrangement and OE number.

• part type: ignition ballast resistor
• selected 1955–1956 Pontiac applications
• selected 1958–1961 Oldsmobile applications
• selected classic Chevrolet and GMC applications requiring a 1.8-ohm ballast resistor
• OE / interchange numbers: 1957154 and 19017084
• nominal resistance: 1.8 ohm

Mount the resistor on a metal surface with airflow because it becomes hot in operation. Connect the coil feed according to the vehicle wiring diagram, including any crank-bypass circuit. Do not use it with a coil requiring a different resistance value.
