Thanks for the link,

I have done a search, and gone through 40 pages or so, back to 2002. Still no answer.

I did find the one about the soldering that you mentioned. I can't see any wiring issue yet.

I tried to read ATC codes, won't work for me.

Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen! Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!
