Picked this up at a flea market for a dollar, looked on Google and could not find a schematic. I see where ground would go on the side of the bulb and a positive to the tip of the bulb but wonder what would go on the screw terminals?? Thanks PS the side of the bulb and tip had sol


dered connections.

 

What model Dixco is it? You might be able to figure something through here

Thanks for that link. My tach is not mentioned but it resembles one pictured there a bit.... I did come across threads on the net but not the one you have. Thanks for that.
