It jumps to 3 upon ignition "on" position. Then, when the engine cranks, it drops toward 0 and immediately returns to 3 with oil psi.

It's quite interesting to watch the guage at operating temp at a stop light. With Brake applied, it quivers at 3. As soon as I release the brake and begin a slow accel, the gauge drops to 1 and begins it accent to 3 with psi...

I am gonna re-check my wiring connection at the sending unit this weekend.

Can anyone give me a tip as to where the wire terminates on the other side?

Thanks
