Gauge electrical question
 

Sorry, not for my Box but for my Miata. Maybe someone of you electrical guys can help anyhow.

My coolant temperature gauge is not working. I know the continuity between the wire coming off the sensor to the gauge is ok, got the buzz from my meter. I have the gauge out. Is there some way to see if the gauge works. When I start the car, it doesn't move at all. Never moves. The oil pressure gauge next to it works ok and I believe they feed off the same ground.

Figured I would ask before I go and buy a part I might not need.

By the way, I am really starting to like the simplicity of the car. Easy to work on, parts are cheap and I don't worry about it.

Thanks.

Miata Electrical Gauge Question
 

Just a suggestion, but you might want to consult with a Miata forum, such as this one:https://forum.miata.net

I was a 96 Miata owner before I moved onto my 986. This Miata forum is excellent. Might be quicker to get an answer from fellow Miata guys. Good luck.

I tried over there. They don't have near the activity we have here. I figured it might be as easy as checking the continuity between the positive and negative going into the switch. Just a guess. Heck, I guess I will just try it. A used cluster panel is $55. Not exactly porsche pricing.

Thanks for responding.

Typically, when testing an automotive instrument you ground the lead attached to the sending unit. If the needle moves the instrument is ok...then the fault lies with the sending unit.
