I am moving this conversation to this forum, for the story so far see:
Summary: On install of a Super Chuffer II, I have an unresolved fault, I get multiple "chuffs" on each cycle of the chuff switch after installing the Super Chuffer II as shown in the following video:
The Locomotive: K-Line K3380-3768G PRR "Torpedo Limited Worlds Fair Edition" Engine w/Tender equipped with Lionel Railsounds and TMCC, listed in the 2002 2nd Edition K-line catalog as part of the K-1204 PRR "The Torpedo Limited: World's Fair Edition" (see: http://www.legacykline.com/app...amp;p_oem_sku=K-1204)
Now, lets review the stock out of the box configuration and behaviour:
Video of stock behaviour:
Video with multiple chuffs:
You can hear the chuffs fall out of time starting at 16 seconds, and it really falls apart at 21 seconds.
I have confirmed that there are no issues with the wiring.
I have 3 remaining possibilites:
I should connect the Super Chuffer circuit to the +5vdc feed from the motherboard (J9 Pin 2)
The switch is bad - although I had the same issue with the a Chuff Generator
as a side not I am not using the headlight ciruit, (H1-P3 & H1-P4) nor the onboard ground H1 P7 on the Super Chuffer II
Any suggestions as to causes?
