Inspection & Review
Before beginning the installation, Inspect the engine and tender to be upgraded
and verify the following are in good working order:
Pick-up rollers
Motor w/flywheel
Smoke unit
Speaker mounting hardware
Volume pot
Coupler mounting hardware, “T” bar, spring, c-clip
Constant voltage lighting board and connected bulbs.
Note: If any of the above items are missing or not in working order, procure the
required parts before continuing.
Note: Before beginning installation, see discussion on page 32 on “wire
management” which should be planned as you proceed during the installation.
Part of the plastic wire tube (R) may be used for this purpose.
Make sure pickup rollers are clean & lubed and roll freely.

Preparing The Tender For The
PS-2 Upgrade
Before you can install the Ps2 components into your tender, any existing sound
boards or reversing units must be removed. The Ps2 Kit contains all the
necessary electronics your locomotive requires to operate. Some existing
mounting brackets may be utilized during the installation of the Ps2 components.
Follow the instructions below taking care to save the parts when noted.
Remove The Following Items From The Tender Chassis
Tender shell (save the mounting screws).
Proto-Sound 1, DCRU Reverse Unit, Mechanical Whistle, Electronic Whistle,
any other electronics and tender harnesses.
Speaker (save mounting hardware).
Existing coupler (save the “T” bar, spring, and c-clip).
Any lights including the rear back-up light and marker LEDs (if present). These
will likely be mounted inside the tender shell.
Do NOT remove the volume pot used on Proto-Sound 1 models.
Remove the old coupler by slipping off the “C”-clip from the coupler “T”-Bar.
If your locomotive does not have a volume pot, order BI-0000040 (volume pot),
IA-0000035 (screw), and ID-000071 (spacer), and IC-0000006(nut).

Mounting The PS-2 Board
Remove the Ps2 Board (A) from the
sealed anti-static bag
Verify Ps2 board is securely inserted
into the plastic mounting bracket (B)
Remove the speaker (K) from the protective packaging (NOTE: be careful not
to damage the speaker cone)
Place the Ps2 board/plastic mounting bracket (A/B) in the tender to verify the
best location to mount the plastic mounting bracket (B) and the metal heat sink
bracket (C) to the tender floor. Also locate a place to put the battery pack (M)
and battery charging jack (X).
NOTE: If you are not a
participating MTH
Authorized Service Center
there is NO warranty once
the bag is opened
NOTE: Use ESD safe work
area and procedures when
handling the PS2 board.
Make sure the Ps-2 board is firmly
inserted into the plastic mounting
bracket. If not, gently push the
board into the bracket until fully
“captured” by the bracket. DO
NOT REMOVE THE BOARD
FROM THE BRACKET.
Place the components on the tender floor in the best position given the space. It
may be necessary to turn the battery pack on its side as seen above.

Mounting The PS-2 Board Cont’d
Once you have determined the best locations for mounting the plastic bracket
(B), metal heat sink bracket (D), battery pack (M), and battery charging jack
(X), mark the tender floor locations using a pencil or silver marker so you can
drill the holes in the proper locations.
Drill the appropriate mounting holes as determined from positioning the Ps-2
board and other components
Remove the Ps2 board (A) with plastic mounting bracket (B), metal heat sink
bracket (D), speaker and battery from the tender and place on an ESD safe area
on your workbench.
Drill the holes as marked with the proper drill size. A 5/32” bit will be required
for the Ps2 plastic mounting bracket (B) and heat sink bracket (C). Use a 1/8”
bit for the battery charging jack mounting holes.
De-burr the holes slightly using a larger drill bit (3/8”) or a deburring tool.
Carefully remove any metal burrs resulting from drilling the mounting holes.
Loose metal burrs can damage the Ps-2 circuit board!

11
Mounting The PS-2 Board Cont’d
Mount the plastic mounting bracket (B) containing the PS2 board (A) using the
2 of the screws (O) and nuts (P)
Apply white thermally conductive grease to the bridge rectifier on the PS2 board.
Mount the PS-2 plastic mounting bracket
Apply white thermally conductive grease to bridge rectifier & metal heat sink
bracket.
PS-2 Upgrade Kit Installation Guide
12
Mounting The PS-2 Board Cont’d
Secure the metal heat sink bracket (D) to the bridge rectifier using screw (Q)
Note, if screw is too long, cut it down so it does not hit the relay
Apply thermal conductive grease to the metal heat sink bracket surface that
contacts the frame and mount to the tender frame using screw (O) and nut (P).
Installing The Proto-Couplers
The Proto-Coupler installs in the same location as the original engine coupler.
Install the proto-coupler (E) onto the existing tender trailing truck or coupler
mount location using the existing hardware. Be sure to route the coupler wire
harness through the tender floor.
Connect black Proto-Coupler connector to black tender harness connector on the
brown & purple wires.
Note: Use coupler insulator as required to prevent shorts from coupler solder
connections to tender truck axle.
PS-2 Upgrade Kit Installation Guide
13
Coupler Installation
A plastic insulator, item EE in the parts list of your Proto-Sound 2.0 Upgrade Kit
has been included with the rest of your Ps2 Upgrade Kit parts.
This insulator should be inserted between
the coupler and the spring, washer and the
C clip that holds the coupler to the T-Bar
and truck bolster. The insulator prevents
the coupler wiring from contacting and
short circuiting against the truck’s axle.
Failure to insert the insulator could
permanently damage the coupler and
Ps2 board.
Shown here is the insulator
attached to the truck and coupler.
Ensure that the part of the
insulator which protects the
coupler’s wires extends up not
down when installed.
Shown above is the
coupler unassembled.
