Position:
•
sensor: relay located in the front recess
of the chassis, to the right
•

Energy is applied for 10 seconds to the
fan relay (36 in the electrical circuit di-
agram, position in the steering head-
stock recess, to the right; however,
CHECK the identification of the relay
with the colour of the cables). Electrical
continuity is required in the wiring for
the relay to activate correctly: no errors
are generated if the relay fails to acti-
vate
