Hot Rods Moon elect. gauge problem ..

showing no pressure , it is showing 7 ohms , do I need new sending unit and if I do what rating do I need ??

 

I have old Moon anniversary gauges in my 3 window that were made by Classic Gauges. I always wondered if they still carried replacement parts?

 

Look closely at the bottom of your gauge. If it says "Classic Instruments" in small letters at the bottom, call then up and order a new sender.

-Abone.

 

Gauge?

Sender?
https://www.mooneyesusa.com/Oil-Pressure-Sender-Units-p/mpgsn52.htm
says "Covers a pressure range of 0-100 psi with the standard 240-33 ohm range. "
If this is what you have and it's showing 7 ohms between the sender connection and the body, you need a new one.

This is just a guess since you mention pressure.

 

This is what I was looking for, thank you very much
