2.
Turn on the fault switch, shorting M- to B-. The lamps should
remain at full brightness.
3.
Move the throttle to at least halfway toward off. The forward
contactor and the lamps should turn off.
4.
Move the forward/reverse switch to "neutral" and then back to
"forward." The forward contactor should not turn on, because the
fault is still on.
5. Turn off the fault switch.
6. Move the forward/reverse switch to "neutral" and then back to
"forward." The forward contactor should now turn on and the
controller should operate properly.
H. If the controller has HPD, test this feature as follows:
1.
Turn off the keyswitch.
2.
Select "neutral."
3.
Move the throttle to about halfway.
4.
Turn the keyswitch switch on and select a direction. Verify
that the lamps do not come on until the throttle is moved
most of the way toward OFF and then moved back up.
I.
Test the controller's throttle fault protection feature by pulling off one of the
throttle's two connections to the controller's throttle input terminals while
the lamps are on (throttle in the ON position). The lamps should turn off.
With the throttle still in the ON position, reconnect the wire. The lamps
should smoothly increase in brightness to their previous level.
J.
Finally, remove the controller from the test setup and check its internal plug
diode, as described in Troubleshooting Procedure
