LGB 65000 Chuff/Voltage

Problem Solving
#1

Hi all:

I run a small analog layout with a LGB Mogul and LGB small diesel. Last year, I added the LGB 65003 to a car behind the diesel for sound. It was very simple and worked great for my purposes. This year, I determined to add a third loco and the LGB 65000, also in a sound car. I added an LGB Forney and the 65000. My problem is that the voltage to run the locomotives does not appear to be high enough to get a chuff out of the 65000. Going around the layout, it only chuffs four or five times. The bell and whistle function without problem but I’m getting nothing for the chuff. Any thoughts?

Thanks for your help!

Dan Pierce is much more knowledgeable than me but if you added a few diodes in series with the motor (actually the bipolar diode strings), maybe that would give you a higher track voltage without the loco going supersonic.

I have several 6500x units and so does a good friend. The American steam version only has the input sensor for chuff capability and if that is turned on then this could be your problem. I have never tried the chuff sensor as LGB did not activate this in any diesel units and I am not too sure if the steam units really work plus the documentation really does not address this, just lists cv settings.

I do not know why LGB published 3 different manuals, but I can tell you that the volume control on the original units was soldered on the board and later units had a cable for remote mounting the volume control.

Manuals did not state anything about whether chuff input was working or not.

CV 55 to 55 is the reset of the decoder to factory settings (no chuff sensing).

CV 64 determines chuff rate, unfortunately you need a DCC system to program this
