TROUBLE SHOOTING
LD27 Green
Fan, voltage = fan activated.
Voltage out, if the LED does not light on activation of the fan
there may be a short-circuit as this circuit has no red LED to
indicate a short circuit. The circuit is short-circuit protected, in
the event of a short-circuit the green LED does not comes on.
Check the fan and cable harness, bear in mind that the fan does
not start until the engine has reached approximately 60
°
C.
LD28 Green
Voltage out, when there is oil pressure.
Voltage out, this circuits has no red LED to indicate a short cir-
cuit. The circuit is short-circuit protected to 165 A, in the event
of a short-circuit the green LED does not comes on. This circuit
feeds many other circuits, so a fault here is difficult to find. The
functions connected here also have their own fuses which
should trip earlier than activation of the short circuit protection
for this circuit. The circuit feeds a number of internal circuits on
the circuit board and also feeds the following. These functions
have their own fuses which should trip before this circuit. The
circuit feeds.
Extra voltage outlets 1 and 2 = J38 and J49.
Traffic kit, outlets J18 and J27.
12V outlet sockets.
