FAULTY MIXTURE OIL INDICATOR

Check oil probe

Take oil probe out of tank, disconnect
connector and connect Tester in “ ”

Tester (+) terminal

coupling 1

Tester (-) terminal

coupling 2

Whilst keeping probe upright, float “A” must run
freely and position itself at the base of the probe:
continuity

Overturn probe: no continuity

COMPLIANT

Check continuity of grounding
of black cable plugged into probe

Disconnect connector from probe and connect
tester “ ” (F23).

Tester (+) terminal

Black cable (1)

Tester (-) terminal

Chassis grounding

(2)

CONTINUITY

White cable between probe and digital instrument
interrupted; repair.
See “Circuit Diagram”

NOT COMPLIANT

Replace oil probe

NO CONTINUITY

Black cable interrupted; repair by providing a
jumper between black cable and grounded point
of chassis.
