Set the output control to maximum and set the sync control to minimum.
NOTE: If at any time during the bench test the display shows OL, make sure that the blue
'brake' wire is not shorted to the 'negative' battery terminal or the white 'battery' wire.
If at any time during bench testing, the display shows Er,
return the unit to your CURT dealer for further evaluation.
Test Standby Condition
Hold the red 'stoplight' wire on the '+' battery terminal. The display should show
a single decimal point. This indicates correct wiring and that the control is ready.
Disconnect the red 'stoplight' wire from the battery.
Test Brake Pedal Activation
Ground the light bulb to the 'negative' terminal of the battery.
Re-attach the red 'stoplight' wire to the 'positive' battery terminal.
The display should step up to 10 and the bulb should start dim and slowly get brighter.
With the red wire still hooked up, slowly move the output control left. The display
should step down to 0 and the bulb should dim and go off.
Slowly move the output control back to the right. The display
should step up to 10 and the bulb should return to full brightness.
