Coil Coupler Upgrade

Installing the tender ElectroCoupler™

B egin the rear tender ElectroCoupler
upgrade (Lionel part No. 602-2957-000)
installation by removing the four screws that
secure the tender body to the frame (see page
11). At the rear of the tender, mounted on the
chassis is the speaker for RailSounds and
SignalSounds. For easier access to the speaker
mounting screws, unplug the RailSound cir-
cuit board as shown below. Unscrew the four
screws that mount the speaker to the chassis.
There is a depression in the chassis right
below the speaker location that has a screw
that holds the rear truck to the chassis.
Remove this screw and rest the truck on the
table. Remove the old magnetic coupler by
compressing the spring under the retaining
clip, then remove the clip with a needle nose
pliers or a flat blade screwdriver. Carefully
release pressure on the spring to avoid
launching parts airborne, causing possible
eye injury. The retaining clip post will drop
off the truck. Then remove the old coupler
from the truck. Install the new ElectroCoupler

by sliding the ElectroCoupler under the
mounting boss. Push the retaining clip post
up and install the spring. Compress the
spring, then insert the retaining clip. Be care-
ful when doing this so the parts do not
become airborne causing possible eye injury.
Next replace the truck mounting screw and
reinstall the speaker. Take the two
ElectroCoupler wires and feed them through
the slot at the back of the tender (see illustra-
tion below). Take the white electrical connec-
tor that comes with the coupler upgrade kit.
Plug the two leads from the ElectroCoupler
into the connector. (It doesn't matter which
lead goes into which opening in the connec-
tor). Plug the connector into the white 2 pin
socket opening on the circuit board. Reinstall
the RailSound circuit board making sure that
both rows of pins line up with the socket.
Finally, replace the body of the tender back on
the frame taking care to make sure that all
wires are inside and do not get pinched.
