<{POST_SNAPBACK}>hi sorry, no im not a previous dcc user, Bachmann class 40, the chip is a TCS, i installed it, its a 8 pin plug type and the controller is the new bachmann Dynamis. hope this helps.
*** Hi Peter
Its not often a chip is bad out of the packet, and TCS has excellent loco control with their new Back EMF decoders, so try this.
If it has a black burn spot, its had a failure and should be replaced. If not, it may simply have a number programmed into it that is not the one you think, so a factory reset may help. So....
(1) First, try a decoder re-set. go to programming mode and set/write CV30 to 2
(2) call the loco up as number 3 - this will now be its number.
If it runs OK problem solved.
If not try (a ) plugging it in the other way round and (
removing the capacitors as advised by Fabben - its very good advice to remove them always as loco's often run much better with them removed...
If nothing helps, return the decoder for replacement - TCS have an excellent no hassle "totally goof proof warranty" and they will simply replace it (or your reseller will on their behalf)
