Caution
Before performing any tests with a continuity light or
ohmmeter, disconnect the component from the wire
harness. This ensures you are testing the component,
not some other circuit.
Interlock modules MUST be removed from the circuit
before performing any tests with an ohmmeter or
continuity light. Battery voltage can damage these
modules if applied to the wrong terminals.
The interlock module senses the position of the safety
switches and reacts accordingly. When at rest the
module will be in the off position and will ground the
engine magneto to prevent the ignition from fi ring. When
the starter rope is pulled, the module takes a small
amount of current from the magneto and sends it out to
the safety switches. If the signal returns to the module,
the connection to ground opens and allows the ignition
to fi re.
Do not attach a continuity light or ohmmeter to the
interlock module or to wires connected to the module.
Current from a battery connected to the wrong terminal
can damage the module. Always unplug the module
before testing any circuits. To trouble shoot the module,
test the switches and wires. If they are good and a
problem exists, then replace the module.
