So other than my drive flange unresloved issue now my oil pressure gauge is going mental :sad0049: its up and down like a mad thing going of the clock - bizzareeeee :sick0019:
First thing to do is check output of battery voltage.
My tacho from Aspro started to act all funny and the next day f................... battery.
Had to go buy a new one. Just a thought. Hope you get sorted.
