New problem cropped up

<< < (2/6) > >>

Josephbw:
Thanks guys, I appreciate the feedback. Yesterday wasn't a good day. I was working on my paint booth and managed to shoot a 1-1/4" brad into my finger with my pneumatic nail gun. It's all swollen up and throbbing and kept me up a lot last night. I still have to do a lot of cleanup in preparation for the arrival of my brother and his 2 boys Friday. He'll be here for about a week so I may not have the time to work in the basement for a while. When I do get the time, I'll let you know the outcome.

Thanks again,
Joe

PS. it sucks getting old, forgetful, and clumsy.  :(

Hey Joe, I resemble that.  ;D

Sorry to hear about your injury. That must have been extremely painful.

The only time I have had one engine pulling on another is when I forgot to set the direction of the second or third engine. I'm sure you thought of that, as it would be very apparent.

Hope your injury heals soon. In my old age fumbling, Several years ago I ran a 1/8 drill bit into a finger. Not funny :-X

The first time I tried to link two locos together I had the same problem as you have. After messing with them for a while, I decided to run them independently for a while before linking them again. That seemed to do the trick as I have never had this problem since. Both locos were Atlas Yellow box GP-40's that were at least 25 years old but never had been run.

Hi

Problem re-occured yesterday, again with new locomotive in the consist. 2 Kato SD40, same gearing, same road number (I renumber one, don't worry) Basically, the same product. Both running à 290 MaH.

Symptoms: Jerky, one pulling more than the other. Vice versa. Slowing down, then back to speed with an acceleration surge. Once stopped and knob turned to 0,00%, one of the loco was still at 9% current, making it pull alone when direction switched, motor still humming after 0,00% got me intrigued so I checked and it was at 9%.  Then, all of a sudden, one of the other loco direction was "mixed up" When on forward, it would go backward, like if I had switched the gear direction, but obviously did not, and then, it automatically went back to normal.

Very odddddddd. I felt like losing control. Which is a no no no.

ideas?

Antoine,

Just have to check, all the modules have the same version of the software in them (and HC software up to date)? I don't know if using different versions of the module software could cause issues like this but it's worth asking.

Your description of doing strange things suddenly almost sounds like something interfering with the signal and the module gets confused, though I see this as quite unlikely.  Might be an idea to set  the motor current to a higher value instead of using the auto reading on the new loco

This could be a Ring Engineering question unfortunately, especially with the unusual "reverse gearing". Never had that one here before.
