Component Testing and Adjustment 7-17TP-5606 6/02
Component
Ohmmeter
Connections
Remarks Results
P1 ground
connection
P1-9 and ground Ohmmeter on R x 1 scale. If good--zero ohms
(continuity). Any other
reading indicates a poor
ground connection.
Low oil pressure
(LOP) safety
shutdown switch
P1-15 and engine block
(ground)
NOTE: J4 and P4 must be
connected to perform this
test.
Ohmmeter on R x 1 scale.
This test is not conclusive
until the temperature
shutdown switches are
checked.
If good--zero ohms
(continuity). Then, disconnect
LOP switch lead and isolate
terminal. Meter reading
reading should show an open
circuit.
High water
temperature
(HWT) safety
shutdown switch
P1-15 and engine block
(ground)
NOTE: LOP switch lead
should be removed and
isolated.
NOTE: J4 and P4 must be
connected to perform this
test.
Ohmmeter on R x 1 scale. If good-- open circuit. Any
continuity suggests that
temperature switch(es) are
defective. Disconnect
individual leads to determine
which switch is defective.
