Coolant System Diagnosis - VStab supplies Temp Gauge 140-160 1972

Dave;

VStab output for the 140s (VDO) instruments is 5.1V (and it can certainly be tested!)...but unless changed for an electronic one which has that as a constant output, and it is still the switching bimetallic element, that means 5.1V long-term average! It is NEVER actually 5.1V! It's either 12V or 0! See: http://www.sw-em.com/voltage_stabilizer.htm#140_VStab_Info

Good Hunting!
