Picked up a pallet of bars a while back. Mostly LED products. Tried to power up the JV2 with the WeCan controller.. Nothing. All connections appear to be intact. The fuses are ok. What says the list in further diagnosis ? LED bars are a learning experience for me, I am mostly a old school halogen tech kind of collector. ( I do have 11 years of basic SMT repair / replacement skills from working at Motorola years ago , Not analyzing although. Just a very rudimentary knowledge of diagnosing in my world. . ) Thanks. Dave.

It is possible that the WeCan module is not properly configured for that bar. Have you booted up the programming on your computer and pulled the configuration from the WeCan module to see how it is set up?

I do not have the software CD. I'll see if I can locate one and give it a try. Thanks.

You can download it directly from the Whelen website as well
Ok. Question. I'm not familiar with LED bars. This batch I purchased is my learning curve. Does the WeCan controller come with a factory setting for the most basic operations ? Or do I have to " turn the controller on " by means of programming ? The controller I purchased was supposed to be in new condition. But.... We all know how that can work out. I could be wrong. But I thought I could power the system up to get very basic operations without programming. As said prior. I'm learning this new way of lighting.

To my knowledge, they come pre-programmed. However, the software will allow you to program for the specific bar you have versus the generic. While unlikely if the WeCan module is new, it is possible that there is no program on it or the programming on it was for options your bar does not have.

Ok. I'll give the programming a try. When I bought the interface. All the trigger , data wires still had the pre cut sheathing on the ends. Now they could have changed out the cables only. The interface appears brand new. Not one indication of scratches or cosmetic give a ways that it was in service. Thanks for your help. I'll give it try after shift this evening.

Ok List, Purchased another WeCan controller. Hooked up to this bar. Nothing. So it appears I have a dead I/O board. Anyone familiar with analyzing circuits on these boards that may have had the same issues I am having ? Thanks.

You have me wondering if maybe it's a sc bar not a wecan bar the two are similar looking no? Nevermind I forgot justice bars are not sc based.... Duh..
