Please tell me what’s wrong with this VU meter..

I’m pulling my hair out on this..

I’m pulling my hair out on this..
I bought this VU meter on ebay to hook up as a the main output indicator after it has gone through the processing chain. – It seemed like a neat idea at the time (I’ve always just had this thing for the glow of VU meters) ANyway, I can’t seem to get it to work.

It wouldn’t have anything to do with the processing gear would it? — I mean is there some incompatibility occurring? Do I HAVE TO put the meter in line before the gear? (I don’t see how that would make a difference really).
I did some research on the net trying to figure out what I’m doing wrong, but I’m not having any luck solving it

I really like it cause it’s a little bigger than the ones I already have, and it’s rather unique looking (I’ve never seen one like it), and I’d really like to use it and am hoping someone here can give me some advice.

I took a close up picture of it, I think maybe this needs to be wired differently or something?

Please advise.

Thanks
(By the way, I still haven’t figured out how to post a picture on this forum)
