Digihat Conversion

This conversion follows the Graham Farish insulating bush (Digihat) method to isolate the lower motor connection from the chassis. The best place to fit the decoder is in the tender. The tender also has track pickups, via a single black wire and the brass connecting bar between the tender and the loco. Be careful to make sure the metal parts inside the tender are isolated and cannot contact any part of the decoder, or any exposed bare wire ends.
