Motor Relay
Testing
I.
Remove the box cover panel. The relay is mounted on top of the motor.
II.
The relay should ‘click’ when the “Raise” and “Safety” switches are pressed
. If there is no
click, check that there is a positive signal on the blue wire when the Raise and Safety
buttons are pressed, and that the black wire has a negative connection. If a signal is
present but the relay does not ‘click’, it may have a faulty win
ding. If no signal is present,
check the wiring and switches in the control handle.
III.
If the relay ‘clicks’ but the motor does not run, hold a screwdriver across the two large
terminals on the relay. If the motor runs now, the contacts inside the relay are probably
faulty and it should be replaced. If it still does not run, the fault is probably either the
battery or the motor itself.
Removal and Refitting
I.
Disconnect the switching wires and cables from the relay, noting their position for correct
replacement.
II.
Remove the screws or band clamp holding the relay on to the motor.
III.
Replace the relay, reconnect the wires and test.
