This is a continuation from another thread that I didn't want to hijack.
I had a junior berk converted to TAS about 8-10 years ago. I recently opened the tender to ensure I had pulled the battery out, and I noticed there was black tape around the edges of the tender base. Thinking it was just leftover from the conversion, I pulled it off. On another thread, I read that it's needed.
First question - why does the frame/base need to be insulated from shell?
Second question - I reapplied electrical tape around the edges, but am now (for the first time ever) having trouble with this engine. Runs great in conventional, but randomly just stops when running in TMCC mode. I'm thinking that it's due to me taking the tape off and, presumably, not doing an effective job of putting it back on. Make sense that's the culprit? Should I go over the tender frame with a fine tooth comb and make sure there's a layer of tape between it and the shell everywhere? Any other logical things to check?
