DCC install question

[Schraddel]

@ Charlie B

Which type of motor are in your sharknose?


This one?
And two of them?
And you really want to toast your decoder  

If this type is really mounted, then get rid of them. They are electric current guzzlers.






And often one brush is not insulated. Meaningly both brush holders seems insulated, but often too the path for the electric current is hidden and not clearly visible.





Here i have replaced this old motor with a Mashima 1833 can motor and the hardened rubber universals were replaced by A-line ones.





And remember, with this brass Diesels one truck is insulated from the main frame and the other is conductive for electric current. Do not interchange the trucks.
And for DCC it will be much better to make additional wipers for a more reliable current pick up.
