Hmmmm..I carefully installed the autometer NV night vision gauge, and started the engine, and to my surprise..the bugger is not working..I didnt take it for a drive, but I reved it up to 1500rpm and it didnt move..I installed the line into the left side "Plug" ..I checked the lines for bends,but see nothing..any suggestions? thanks...

 

Take it for a drive. I thought the same thing. Put under a little load and it will move.

 

If you put it under load it will work then.
