Omori oil temp gauge fitting problems


AMG

Recommended Posts

I have fitted an omri oil temp gauge and cannot get it to read anything. I have fitted the probe, no problem, and fitted the wires i know correctly but now struggling for ideas of how to get it to read anything

 

Wires at back of gauge:

Orange

Yellow

Red

Black

White

 

Wires on probe

 

Orange

Yellow

 

Connected yellow and orange to the probe, black is ground, white is illumination. That leaves red which i thought was a positive in wire. Connected it to a known + and the needle on the gauge shoots to the top of the scale and stays there.

 

Anyone have any ideas of how i can sort this out?

 

Also connected the known + to the yellow wire and blew a fuse, oops.

I am guessing that as the probe wires are the same colour as the wires on the gauge that they are correct :search:
