Checking thermal engine room switch
1) Disconnect connector of switch and connect
ohmmeter between terminals on switch side.
2) Make sure that switch is “ON” (ohmmeter
indicates “Zero” ohm) when atmospheric
temperature is below 7°C (44” F) and “OFF”
(ohmmeter. indicates infinity) when above
(67”
Checking high altitude compensator
Check the compensator as follows:
1) Disconnect the coupler of compensator and
connect an ohmmeter to the compensator.
2) Check to be sure that;
If the altitude of the place where this check is
performed is above 1,220 m (4,000 ft), the
ohmmeter should indicate “Zero” ohm
(compensator is ON).
If the altitude is below 1,220 m (4,000 ft),
the ohmmeter should indicate infinity ohm
(compensator is OFF).
3) After checking, connect the coupler.
