TCS 1628 WM-MB2 from TCS 8-Function 21-Pin Decoder HO Scale

This motherboard is specifically designed to replace the original lighting board in the Walthers Mainline EMD SD70ACe diesel locomotive.

 

Included on this motherboard is a KA4 Keep-Alive™ for smooth operation over troublesome tracks. Pair with a WOW121 for unparrelled sound and interruption free performance.

 

NOTE: This product does not function without a decoder. Pick up an EU821 or WOW121 diesel decoder to use this product.

 

NOTE: TCS motherboards feature on-board resistors for use with LED's. This product is NOT intended for use with incandescent bulbs without modification and/or an external power supply such as the VR1.5.

 

6-Pin Harness Note: The WM-MB2 was designed to the original specifications and pin-outs found in the Walthers Mainline SD70ACe, except for the 6-pin connector which does not match NMRA color-code specifications. In order to install this motherboard in your model, you will also need to use the corresponding harness. The 6-pin harness is included in the package with the motherboard.

 

2-Pin Plug Note: The WM-MB2 has several plugs for connectors to interface with the functions of your locomotive. These plugs should be included from the factory. If your model does not include these harnesses, or you would like to install your own, they may be purchased separately.
