(6)
Set multimeter for ohms, and connect positive lead to temperature sender terminal and negative lead
to pin 4. Multimeter should indicate as follows:
At 70°F, ohm range is 108-111ohms. For each +10°F, add two ohms to either end of range. For
each -10°F, subtract two ohms.
Example:
At 80°F range, should equal 110-113 ohms.
At 60°F, range should equal 106-109 ohms.
(7)
Connect negative battery cable to battery.
(8)
Start up generator set, paragraph 2.11.1.
(9)
Allow engine to operate while observing multimeter. Ohms indication should decrease as
temperature rises.
(10) Shut down generator set, paragraph 2.11.2.
(11) Disconnect negative battery cable.
(12) If indications are not as above, replace coolant temperature sender (2). Refer to paragraph 4.13.2.
