Perimeter Lighting

ENT2B3(x) Intersector Light Does Not Operate Correctly

For any failure, begin by checking that all wire connections (pins in connectors) are engaged to ensure a proper connection.
To determine which part is not working, (the light head or the potted controller) unplug the controller from the light head.

With an 8 – 9Vdc source (a 9V battery works well), connect the negative lead to the Black wire from the light head.  With the positive lead from the 9 – 9Vdc source, momentarily touch the Red, White and Green wires going to the light head one at a time.  AVOID USING A 12Vdc SOURCE TO TEST THE LIGHT HEAD, BECAUSE IT WILL CAUSE DAMAGE TO THE LIGHT HEAD. You should see three LED’s turn on with each wire.  If all three banks of LED’s do not turn on, the light head may be defective.

To check the potted controller, apply 12Vdc to the input Red wire and connect the Black to ground.  Monitor the output (Red, White and Green wires) with a scope or DVM.  You should see a pulsing DC voltage.  If you do not see a pulsing DC voltage, the controller may be defective.

NOTE: your DVM may not be fast enough to lock onto the the actual voltage number before the controller switches, but you should see that it is changing states between high and low voltage.

Vehicle Flashers

To Verify Flasher Operation

With the flasher power and ground connected correctly, with the Blue & Yellow wires disconnected, apply power to the flasher power wire and control wire (in most flashers Red wire).  With a DVM, you should see pulsing voltage from each output wire (Blue & Yellow).  With a test light, you should see the light flash on and off.  If no flashing occurs, the flasher may be defective.
