Ignition Ballast Resistor RU10
Resistance (OHM): 1.77 - 1.87 Ohms at 70° - 80° F
Use with coil UC12 (# 4931291) in applications with starting bypass circuit.
TIPP: GM vehicles have the ballst resistor built into the main engine wiring harness. If there is trouble, which is rare, we suggest taping up the old wire and running a new wire to this RU10 resistor. This is much easier than opening the harness.
