Whelen Liberty (WeCan) problem

[#1texan]

Looking for some assistance with a Wecan Liberty bar. It is wired to a universal control point and when powered on nothing happens. I have ruled out the control point as the problem (hooked it up to another Liberty Wecan bar). I also took the top off and check the fuses on the I/O board (all good). So I'm thinking that it is probably the I/O assembly, any other ideas on what else it might be or how to determine if it is the I/O board for sure?

Also this was purchased as a used bar and is no longer covered by warranty.


Thanks in advance for the help.

If the I/O board is getting + and - 12VDC to the large red/black wires at the connector and the wecan cable is sending signals to the I/O board then is sounds like the I/O board is the problem.

There's also a couple 20amp fuses that are worth a quick check

If you haven't already, you need to create a new bar under the WECAN programmer software, then send the blank file to the lightbar. Once you've done that you should be able to program the bar normally. I had the same issue with a TXDPS liberty that I bought and tried to use the universal control point with
