Oil Chex Gauge

[Graham Freeman]

Thanks for the response deuce lover.
After looking at the gauge (from the front) again with the face plate off there is a wire internally that runs from the top left down to the bottom left obviously the jumper you speak of.
So that means the other one at the top right goes to the oil pressure sender.
The other bottom one on the right side is the out (or in) for the amp meter depending on which way around the wires are connected.
Obviously the order they are connected means which way the gauge reads because of flow direction.
Am I correct?
Thanks Graham
