You commented on a post of mine about an etcher. I have the ground from the transformer and hooked up a ground on the side like the plans showed. Are you saying take all of the grounds loose. I put a meter on it and I get 24 volts ac but when I switch to dc the meter read -24 volts so I swamp the meter leads so the ground was on the read lead and the positive was on the black lead and it read 24 volts. When I etched it went into the metal but not very deep and filled my stencil with brownish gunk and also marked the metal but it wiped right off, this was on dc settings. Any suggestions would be much appreciatted. Thanks Holland
