This installation documentation is for the HO-Scale IHC 2-6-0 Mogul. This installation uses the WOW121-Steam decoder, B-MB2 motherboard, and 28mm WOWSpeaker. In this installation, the speaker has been substituted for a High Bass 28mm speaker.
To make the connection between the locomotive and tender, a TCS 6-pin mini connector was used.
The IHC 2-6-0 Mogul shown with the shell on.
To start, first remove the red highlighted screw on the drawbar and separate the tender and locomotive. Next, remove the red highlighted screw in the front of the locomotive. Finally, remove the middle screw for the draw bar.
With the front screw removed, remove this second screw and the locomotive shell will lift up off of the frame.
With the loco shell off, remove the frame piece that holds the motor in place, being careful to keep the components in order.
Solder new motor leads to the motor points shown above.
After carefully lifting the motor out from the chassis, solder to the track pickups shown above. Note: This image shows the wire leads then fed under the motor mount mount clip.
In this installation, we added super bright, long lasting TCS Golden White LED's. To do the front, simply remove the boiler plate. The original bulb will pull out from the back side and new LED can be inserted in it's place. Feed the wire leads back from the locomotive body.
Another view showing the LED installation.
Splice the new harness into the locomotive wiring leads, including the new LED headlight. Replace the motor and clip in place. The locomotive is now complete and can be set aside to work on the tender.
There are three tabs holding the tender shell on. Release these and the tender shell will come off. Shown with the shell off.
Wrap the Keep Alive caps on the bottom of the B-MB2 with TCS Kapton tape sku#1256 to prevent shorts and using foam, double sided tape, mount the motherboard as shown on top of the existing weights.
On the opposite side of the weight, using the same tape, mount the WOWSound Hi Bass speaker facing up and solder the wire leads to the motherboard along with the tender track pick up and new wire harness leads to the motherboard.
The tender installation shown complete. You can now close up the tender and locomotive and your IHC 2-6-0 Mogul is WOWSound equipped and ready to run!.
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
Other solder tips
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
