Wheel Drive System
Testing the Reverse Button
1. See Figure 9
. Disconnect the Handle Harness
(H)
from the mating connector located to the left of the squeegee
raise/lower handle.
2. See Figure 8
. Use a continuity checker or ohmmeter to check the continuity between pins 3 and 5 on the
Handle Harness
(H)
. When the reverse button is working correctly:
• The circuit through pins 3 and 5 should be open when the reverse button is released.
• The circuit through pins 3 and 5 should be closed (approximately zero ohms) when the reverse button is
pressed.
3. See Figure 9
. When you’re done checking the reverse button, reconnect the Handle Harness
(H)
to the
connector on the machine.
