How do I reset the chuff rate on a K-Line Tank engine?

I have the info some where to re program chuff rate.  I'll get back to you

Thanks Gary

To change the chuff rate di these steps:

HIT DIR, WHISTLE, AUX1, then the chuff rate of 1,2,3, or 4.

funny thing is there was a day where half me engines had Kline cruise, now I'm down to one engine.

Here is the text of a reply that I received in reply to a similar question that I asked several years back:

 I received my Tank Eng and it had the erratic chuff, sounds like a machine gun with the smoke unit turned on, with it off no problem. So here is my fix and it works. Take top of eng and look at smoke unit. There are 2 wires going to fan motor, one green and one yellow. Unsolder the green at the motor and remove the other plug end at the circuit board. Now add a 1n4004 diode as seen in picture to the green wire. Solder the band end of diode to the fan motor, put some plastic tubing on the diode so it wont short out and plug the other end back into the circuit board. I find it cures the rapid machine gun sound. My eng has been running for 2 days now and no problems. At 4 chuffs programmed in, at slow speed it’s ok, but I find with 2 chuffs programmed in it sounds better.

Joe at Just Trains reports that a diode in the yellow wire also solves the rapid-fire chuff problem.

Go to Radio Shack, they will have it. And if they they don't use a 1N4001 or a 1N4002. I believe the 01 is rated at 25v and the 02 is rated at 50v. You just want to cut the sign wave in half.

Here is the part number for the diode from Radio Shack:

1N4004 Diode

I would highly recommend using Heat shrink tubing instead of tape over the entire diode and leads.

If you would like me to forward you the email, please contact me at my screen name at Ay Oh El dot com.  You can figure out the domain name.

Rich is right, the tank engine was a unique case and it has issues with the smoke fan motor affecting the chuff input.

I've installed many a diode in those engines but that's not Scott's issues (doesn't look like the smoke unit is on in the video).  For some odd reason the Kline cruise sometimes gets scrambled and it goes like to a chuff rate of 20 requiring you to re-select the chuff rate.  If I recall i might of installed the diode in Scott engine, maybe not been a long time.

My last kline cruise engine sometimes looses the selected chuff rate just like Scott's requiring you to reselect the chuff rate.

In that case , the reset sequence should get it's mind right.

Gary's fix was the correct. I purchased this at York in October from Eastern Depot. They fixed the diode before they sold it to me.

Thanks for everyone's input.

Guys,

Was this an issue with all of them?

Every Kline cruise equipped engine I have had sometimes, but not often, I would have to reset the chuff setting.  So in my experience yes.  I'm down to one engine with Kline cruise.  A Kline Mikado with a puffing smoke unit.  If I ran it more I'd convert it to ERR RR cruise, but as long as it works and only occasionally hiccups it's not worth it to me.  The reset is easy to do as listed above.

Gary,  So you could change the chuff rate on K-Line Cruise engines even if they used the cherry switch to trigger chuff?  G
