Default Re: AVO VCM 163 Meters

Hi Martin,

Thanks for the detailed reply, and I'm glad I am not the only one to have experienced this meter movement anomaly. I belive the meter movements to be original and the resistance for current meter is 2.4k. I have taken some photos of the Ia meter removed from the case, there does appear to be corrosion and the set zero adjustment was hard over to the left as viewed from the front, that is the only way it would zero correctly.

Something makes me wonder if the hair springs are working correctly, tipping the meter on its side alone makes the needle move right accross to the FSD position by gravity alone, is that normal for one of these? The way the needle appears to move is that there are no springs in place at all, or extremely weak ones.

Please see the photos I've taken, I will take more when I get a chance.

Look forward to some feed back,

Thanks Martin.
