Erratic SPA DG gauge


Rummy

Recommended Posts

I have two of these Dual gauges, one for fuel pressure/oil temp and the other for oil pressure/water temp. Now the problem is, lately the oil/water gauge just jumps to max temps and stays there for an indefinite period then occassionally flicks back to reading normal.

 

I've checked the connectors on the gauge and the earth and power feed. Both gauges use the same earth and power but only the oil/water gauge goes full retard. Faulty gauge? As it cant possibly be both the sensors, can it??

 

Any ideas as it's driving me nuts! :confused:
