Upgrades
T
his upgrade is made using kit 6-22957.
One upgrade kit is required for each F3-A
unit. With the cab removed, begin by replac-
ing the old coupler and routing the leads
from the electrocoupler through the pilot
and frame as shown in the upgrade kit
instructions. Once the wires are routed,
install the coil coupler leads into the white 2
pin connector included with your upgrade
kit. See illustration below for correct installa-
tion. Plug the connector into the main cir-
cuit board at the locations for the powered
and non-powered F3A shown. Finally, make
sure the wires are clear of the motor and the
truck guides. Neatly bundle them using twist
ties for added protection and reinstall the
cab.
