The cam switches (blade style for the A through K, microswitch after) are faulty - common symptoms are 8/10A Slo-Blo (1A Slo-Blo is OK, nothing higher please!) fuse pops and the gripper motor is jammed. ![]() ![]() With an ohm-meter (resistance) set to the lowest setting (200R or less) a good switch will show about 0.2 ohms (0R2) resistance - remember to check the lead resistance first and to mentally subtract that from any reading - probes shorted should show about 0R2 to 0R4 (ohms). A point to consider when testing switches is if the switch is still soldered into the circuit when the switch is open it still may indicate a short as an switch somewhere else in parallel with it may also be closed (cancel circuits for example) I am using the convention that the letter 'R' is used to indicate the period place holder when measuring resistance. I recommend using a healthy pair of alligator jumper wires that with one end on each of the probe tips, and the other to grasp the lug of the switch in question and read the resistance when the switch is both open and closed.
