My egt gauge needle points straight down and does not move. I know it is hooked up right, because a few other gauges are wired to the same places and they work fine. In addition, I had to drill out the ring terminals to fit over the treaded studs on the back of the gauge. Did anyone have this problem? I know my needle has taken some blows and has some small dents and scrapes on it. I am trying to trouble shoot the problem and could use some help.

this is probably the wrong forum for this, i have reposted in the turbo forum. please disregard.
