This motherboard is designed to replace the original lighting board in Intermountain and Bowser diesel locomotives. Created to fit the Intermountain SD40-2 as well as the Bowser C-636, the IB-MB2 will fit a wide array of other locomotives. However, it will require comparing the original light board as there are a few styles of Intermountain/Bowser motherboards which look very similar. Included on this motherboard is Keep Alive® for smooth operation over troublesome tracks. Pair with a WOW121 for unparallelled sound and interruption-free performance.
NOTE: This product does not function without a decoder. Pick up an EU621 or WOW121 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 or an external power supply such as the VR1.5.
The IB-MB2 has plugs for connectors to interface with the functions of your locomotive. If your model does not include these harnesses, or you would like to install your own, they may be purchased separately.
