6. Use a multimeter to measure the voltage across the main contactor posts as
follows:
A. Position the rubber boots away from the main contactor posts to get
access to the posts with multimeter probes
B. Connect the multimeter common (-) test probe to the ground connector in
the work light connector (step 5).

D. Turn the key switch to the S
then turn the key switch to the R
click as it is energized.
E. Use the second multimeter test probe, check that all 4 posts on the main
contactor have system voltage (42 V to 64 V @ 100% state of charge)
present (Figure
present, the contactor is damaged. If none of the posts have voltage
present, ensure that common (-) test probe is still connected to the work
light connector and if so, look for electrical issues at other machine
components as the contactor is not being energized correctly.
F. Turn the key switch to the O
as it is de-energized.
