DIODES
An internal IFB board diode (D6) and the external
diode (D 5) are used to prevent fly-back voltage
from the 24 volt and 12 volt circuits. The D6 diode
is located under the IFB board fuse cover and is in-
stalled in the board fuse holder JP-2 location. The
external D5 diode is located tied to the main har-
ness adjacent to the IFB board and is installed
from the factory in the #3 pin location of the IFB
board with the other side of the diode connecting to
the 033A wire of the main harness. Before replac-
ing an IFB board due to loss of 24 volt or 12 volt
power, the Diode circuit should be checked for an
open circuit or reversed wires or fuse terminal con-
nections.
