Starter Solenoid
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the test leads together. The me-
ter will display a small resistance value (usually 0.5
ohms or less). This resistance is due to the internal re-
sistance of the meter and test leads. Subtract this value
from from the measured value of the component you are
testing.

With the traction pedal in the neutral position and
the switch button depressed, resistance should be less
than 1 ohm between the terminals.

With the traction pedal in the the forward or back-
ward position, there the meter should read infinity
ohms across the terminals.
