C13 (U33 now the most current R2LC, used in all new production Lionel stuff with RS 5.0 and Odyssey)
Interesting. The board I swapped out of another unit to check if the C07 board was the problem was a C13. The unit was a Weaver brass Hiawatha that has got to be 10 years old. I wonder how that board got in there...
Thanks guys. I'll try a C08 board in the engine and see if it works.
The engine in question is a Weaver brass Hiawatha Atlantic. With the tender shell off, it was barely responsive to commands, taking a long time to respond to the throttle and not recognizing some commands at all. With the tender shell on, it didn't work at all. I checked tender shell isolation, which is OK. It worked fine with the R2LC out of the Hiawatha Hudson and the shell off. I haven't had time to test it with the shell on but will probably get to it tomorrow or Monday. I'll post the results.
