On the thermistors what does ntc mean and how do i test this I have an auto ranging test meter but im unsure what to do & do i still test this with no power on.
NTC - Negative Temperature Coefficient (Resistance decreases with increasing temperature)
PTC - Positive Temperature Coefficient (Resistance increases with increasing temperature)
Thermistor - Wikipedia, the free encyclopedia
Best to test the thermistor out of circuit i.e. with the wires/leads to the PCB removed. Otherwise you may be measuring other stray resistance.
You place your multimeter in resistance measuring mode (usually kohms) and touch the 2 multimeter probe tips either way round across the thermistor terminals.
its an ecotec only one thermistor/NTCcheck thermisters on ch side are ok also
flow turbine and diverter
