I just bought a rebuilt Scott DCC fitted for my DC layout, I got the loco as it is weathered and was only £70

I have a Bachmann DCC 9F that runs fine. The Scot doesn't always start straight away which I believe is due to the chip kicking in when there is correct volatage, and if I change direction to reverse it tends to go the forward still then revert by itself to going the right way, reverse.

Can anyone give me tips on sorting this problem out, and if it means removing the chip, so be it.

also, if i have toremove the chip, I have a green chip that came with my Bachmann DCC 9F, is this the blank one?

and if so can I put a Bachmann Blank in a Hornby loco

Really appreciate any help.

*** The Hornby chip is not all that happy on DC.

Remove it and insert the blanking plug that you took from the bachmann. All 8 pin sockets are the same so the blanking plugs are universal.

If you ever need to unchip a loco with an 8 pin socket, and can't find a blanking plug, then you can also just use a bit of brass or copper wire between the top 2 pins and another between the bottom 2 pins like so

Before you add a new chip, remove the capacitor(s) from the hornby loco - The chip will perform better without them.

My new T9 is chipped, although don't have DCC control, and it runs fine on D.C. Richard( see youtube vid in T9 topic post)
The loco moves with just a tweak of voltage, no hesitation at all, and reverses immediately.
I have not touched it at all, is exactly as delivered.
It seems very happy on DC

*** I'm sure it does, but the Hornby chip is very sensitive to the type of DC controller used (They have wildy different outputs, from pure DC to various chopper/half wave circuits that many decoders cannot cope with... and the hornby chip is very sensitive to some of them).

This was so extreme with the earlier versions that hornby themselves at one point advised / recommended that chipped locos not be run on DC!

It also varies depending on the software version of the hornby chip.

Understand that your experience is far from general, with the majority having some issues. The T9 has the latest chip, the Scott had a different one. Your controller may be different to the threads initiator.

With each iteration the hornby chip gets better, which is a positive thing... but it still remains a poor relation to any chip from any of the specialised mfrs.

QUOTE my DC controller is a very old Gaugemaster unit circa 1996/7?

I agree that this "old" but not "very". I'm sure I'm not the only one who as a 1976 H&M Duette ......
and I'll bet there are older ones that too - and my DCC equipped (Lenz / Zimo) locos ran very nicely with it before I got my ECoS.

David you are so right, I am the proud owner of TWO H & M Duette's


Kind regards
