Testing a Federal Signal Unitrol 9000

[fedsig7]

Im trying to fully test my Unitrol 9000. The siren works, the slider works, but I can fiqure out how to test the 6 black & white switches on top of the control head, there are about 10 yellow wires coming out of the back, and those are connected to the switches I need tested. I have tried wiring them up with a light bar, but it still is not working. Is this the wrong way to test them? Anyone have any ideas?

If your power supply couldn't handle that load, it may not. Try testing something like LEDs on them.

Okay, I dont have any LED's right now. What do you think about a rotator bar?

Again, depending on your power supply, if it can't handle the load, then it would appear as if the switch didn't work. Try something that doesn't draw many amps.

Okay, thanks

If the switches are connected to a power source, use a voltmeter for testing. If the switches are not connected to a power source, use an ohmmeter for testing.
