1998 Baja 180 Islander w/5.7 liter 250 horse. What exactly is the purpose of a "slave solenoid" in the starting circuitry? Where would I find it, is it different from the solenoid on the starter itself? I occasionally get a no-start - nothing when I turn the key but the guages come alive and I can hear a faint clicking from the engine area. Battery tests good. I am replacing the battery cables because they do have quite a bit of corrosion. Any ideas? Could it be the ignition switch itself? Thank you for any of your thoughts.
