Intermittent Defi oil pressure gague
 

Over the past couple of months my Defi oil pressure gague has been alarming up, sometimes it would be ok for a few days other times it's on/off throughout the journey. It has gradually got worse to the point that it spends more time buzzing it's t#@*s of than it does working :mad: . Thought it was the wiring in the plug on the back of the control box. so i hard wired it in, still N/G, swapped wiring between gagues still N/G, checked wiring at the plugs that join the cables together under the bonnet all seems ok. :wonder: Is there any way of checking the sender unit Voltages etc

Oil temp gague is working as normal, oil level ok (changed 2000 miles ago)

Assume oil pressure is ok, original sensor still fitted and no alarms, plus engines not gone bang.

Anyone
