Good morning!

I have an Arjent s2 with a SIM and smart siren LMS. I wired everything up and tested it on a different arjent bar and everything works as it should. I hooked it up to my bar and nothing. I can’t seem to figure out what the issue is. The smart siren powers up just fine and all the relays click (and like I said it powers up a different bar) but can’t seem to getmy bar to light up.

Any suggestions? Common power issues with arjents? Fuses that usually blow?

thanks in advance!

I've never worked on an Arjent before, but I did some looking around. There is a control board inside the light bar that has FOUR 15 amp fuses on it. Might check those fuses. If they are blown you may want to figure out why before you install new fuses and apply power again. If you don't see anything wrong (shorted wires or anything) you could try replacing the bad fuses and see what happens. Might check the power wire connections inside the light bar, too - just to make sure the wires are all connected securely and plugged in and not corroded or anything. Here's some pictures of the control board. I'm not sure where on the light bar it's located though. Let us know!
