Hello All,
I recently found an old Weaver diesel in my collection with a TAS Railsounds system. The loco runs great on analog but will not take commands of any kind. When I pulled the radio board off, I discovered a wire underneath had been cut. I am thinking this may be the antenna wire but I am not sure since I did not make the cut. Does anyone have a wiring schematic for the TAS boards? Can these accept the ERR cruise control upgrades?
Many thanks,
Mike

Hi Mike,
There's a technical documentation section within this site. Follow this link to the TAS documents:

It should help, but you'll see that you have a number of choices. We'll need more details on your diesel to point you to a specific document. Pictures of the control board(s) would help.

I could be wrong but I thought the ERR upgrades were the boards from TAS. Am I wrong?
Thanks Mike,
Looks like I have the EOB board BUT I am missing the tach sensor, that is the wire that was cut. Anyone know where I can buy a tach sensor and tape? I still do not see an antenna on the Cruise Control motherboard. What am I missing here? I did not realize this one was a cruise control borad, this would negate the need for the ERR upgrade providing I can find the pieces to get her up and running.
Oops, after a second look I have the DC SAW board and the antenna wire is the one that was cut. So I have to figure a good way to make one. I know the "antenna" on the ERR is basically just a wire but it seems like the earlier stuff had an actual piece of brass that the lead wire was soldered to. So if I want to convert to cruise control, will this board accept the ERR modular option? Thanks again all!!
Although it is possible to "skywire" a CC-M into the TAS SAW board, I'd consider replacing it. You could consider a Lionel diesel motherboard, transplant all the Lionel boards from the SAW, and add the Cruise Commander M motor driver. Alternatively, you could just do the Cruise Commander and find a small steam RailSounds motherboard to mount the two sound cards on and go that way.
John, you always have the answers! Thanks for the advice. I think the only thing I do not like about the TAS board is the super high speed, not really appropriate for my 2 rail scale pike. I love the old Weaver Alco FA-2s but was not thrilled with the China drive model but when I found one lurking in the attic I thought it may be worth a shot at putting it into service. With ERR cruise I believe it would really run great and I could switch out my industries without fear of overshooting the siding and sending everything to the hardwood floor! 
At least some of the answers.
