After a few years i got out the fowler tank loco, on test it ran with a squeak, so did the usual thing and gave it a touch of lube here and there, the main gear from the motor was very dry to start with, i also cleaned up the pick ups which are strips that connect to two points, re assembled, easy enough, and now it dosent run at all,dead, cant think what ive done wrong here, on assembly made sure that the pick up points aligned with the two connections, i discovered it has a dcc chip, no dcc here and never had a problem in the past, all ive done since then is checked continuity, there is connection from wheels at one side to the earth point on top near motor, the two connections at the other end of the motor are no contact from anywhere, of course they go though dcc chip first i would think, i know nothing about dcc chips, i am no stranger to resurecting locos, and have done with old school ringfields x04's and spider motors many times, this one has me a bit stumped, can anybody help prevent this from becoming a mantlepiece ornament.
