4. While sitting in the seat, follow the procedure below
to test the delay module function.
1. Disengage the parking brake.
2. Pull the right and left motion control levers out of
the neutral position.
3. Turn the ignition key to the RUN position.
4. The meter should read approximately 12 volts
DC.
5. Lift off the seat or disconnect one of the seat
jumper wire leads. The meter should hold
around 12 volts and then read 0 volts DC after
approximately 1 to 3 seconds. This test shows
the delay module is working.
5. If you do not get 12 volts DC at the violet wire when
turning the ignition switch to the RUN position, verify
the following:
1. 12VDC at the Tan wire terminal.
2. 12VDC at the Brown wire terminal.
3. 0 VDC at the Gray wire terminal.
4. If all these conditions are met, replace the seat
delay module.
