Note 1 - The F4 must be in place for Prestolite
alternators to charge. It must be removed for Bosch
alternators. Note: Service parts interface boards
are shipped without F4 fuse.
F10
There are three in-line fuse clips that allow for
two configurations of the F10 fuse. The upper
position is the normal position. When fuse F10 is
installed in the upper position, control power is
routed to the K9 On/Off Relay contacts. The On/Off
keys on the HMI control panel energize and de-
energize the K9 On/Off Relay. When the K9 On/Off
Relay is energized power is supplied through the
normally open K9 contacts to turn the unit on.
When fuse F10 is installed in the lower position
power bypasses the K9 On/Off relay contacts and
the unit will start and run without the HMI control
panel. Do not operate the unit with the F10 fuse
installed in the lower position unless absolutely
necessary.
IMPORTANT
If fuse F10 is installed in the lower position the
unit will start and run. The HMI Control Panel On
and Off keys will not function. The Off key will
not turn the unit off if Fuse F10 is in the lower
position. If Fuse F10 is in the lower position it
must be removed or the Microprocessor Power
Switch must be turned off to turn the unit off.
F15
The device identified as F15 is a poly switch.
This overcurrent device resets automatically and is
not replaceable.

Important: Do not attempt to remove the relays
from the interface board.
