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.

In this conversion, the customer required the decoder to be easily removable, hence the use of a 6-pin harness in the tender instead of the hard wired decoders normally used.
