This installation is for N Scale Fleischmann 7324 Electric Locomotive Class 146 uses TCS EUN651P-30 digital decoder and was performed by A.G.

The pictures above show the locomotive prior to the decoder installation.
First remove the shell by squeezing it on either side of the plastic covers and gently rocking it back and forth until it slips off the frame. Here is a picture of locomotive's 6Pin NEM socket where the DCC decoder will be plugged. Pin#1 (Orange wire) is marked on the "dummy plug."
Here is the close-up of the "dummy plug" where the Pin #1 is marked.
Remove the "dummy plug" and insert the EUN651P-30 into the 6-pin socket. Make sure that the decoder wire orientation is exact with the one shown in the picture above (orange wire to the left).
We use 1/4" Kapton tape that was placed around the decoder to make sure it will not cause the short between the decoder and locomotive's chassis. Put the shell back together and we are ready to run this engine.

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 than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than 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.
