Silver Direct Locomotive decoder
Some advice on installing the decoder:
Although the SILVER decoder has many internal safeguards to prevent damage, you
must not allow any metal part of the locomotive to touch the surface components of the
decoder. This could cause a direct internal short circuit and the decoder will be
destroyed. The motor brushes MUST also be completely isolated from the rail
pickup. Achieving isolation may require some different approaches on different
locomotives, perhaps unsoldering wires or placing a thin piece of insulating plastic
between the motor and the locomotive frame. If you have a VOM, check for infinite
resistance between the motor and all the wheels. Take special note that a short might
occur when the loco body is reinstalled.
DO NOT WRAP decoder with electrical tape or shrink wrap!
Doing so will impede air circulation and degrade the performance of the decoder.
Instead, put electrician tape over any part of the locomotive frame or body that might
touch the decoder and use double sided foam mounting tape to mount the decoder.
This will prevent short circuits without 'suffocating' the decoder.
The SILVER decoder can not be set up for simultaneous use for 2-rail pickup and
overhead cantenary or trolley operation. If the locomotive is turned the wrong way, the
decoder could get twice the track voltage, which would destroy it!
Wiring Options
The Silver Direct is designed for locomotives that have an NMRA 8 pin socket. To
install simply remove the dummy plug from the locomotive and plug in the decoder.
Step by Step Installation
To install the decoder simply remove the dummy plug in your locomotive and install the
decoder plug. To ensure the headlights work correctly you must align the plug properly.
Pin 1 of the plug connects to the orange wire. Ensure this is aligned to Pin 1 of the
locomotive. If the plug is installed wrong way round the lights will not work. When
installing the plug ensure that the pins are not bent or broken.
