Dont worry I did use a blanking plug!
It stands to reason that 9 volts will not generate the top speed. I find that one of the minor frustrations of running DCC is that one still seems to require a DC control system to diagnose issues like this one! Not something that is commonly discussed...

Well I finally purchased a new 9V battery and tested this loco in DC. It still runs only very slowly so clearly there is no problem with the decoder which really suggests the motor is the issue. I would have thought that a motor either works or it doesn't. Any suggestions about what might cause this...

I have already tried resetting the decoder more than once, to no avail. Running in DC is not an option as I no longer have a DC controller.
Will have another go at changing those CV values though. I think I set CV5 at the maximum 255 instead of the minimum?

I have a Bachmann cl.80 tank loco, DCC fitted, which will not run at much more than crawling speed. The speed does not change beyond about about step 11 on my NCE Powercab. This has previously been one of my best running locos and the wheels & contacts all seem clean. I have tried swapping decod...

So this is my effort at wiring up each relay - quite a lot of fiddly soldering required! https://i.postimg.cc/cKxkW8Xh/GM500-Relay.jpg After fitting four of these to their associated points and signals, none of the relays would work. A careful re-read of the Gaugemaster instructions indicated that w...

They include several different resistance values simply to provide a choice of lamp brightness.
I guess this depends on the period being modelled - for those that are really particular!

Thanks Brian.
How critical that the resistor is 5k ? The shunt signal is supplied with several resistors, 7.5k, 10k and 15k.

I have recently purchased several DCC Concepts ground signals that I was intended to control using Gaugemaster G500 latching relays (to be activated by the point motors). I now find that the signals only have two wires but the relay has 3 outputs. I have a separate 12v DC power supply for the signal...

Thank you for that.
I see that Gaugemaster also have very useful wiring diagrams on their website. Exactly what I needed to understand!

I am thinking of using latching relays to control DCC Concepts ground signals - so I can control each signal from the same momentary switches that activate my Peco point motors.
I have never used relays. What type should I be using and where does one buy them?
