Well, I opened the tender and indeed the tether is completely hardwired to the boards, there is no simple plug at the other end. After fiddling with the tether and plug that connections to the engine while it was running, I found that there may be a wonky wire within the tether cable. I rotated it a bit at the cusp of the tender and "locked it down" and it seemed to remedy the surging, but it's obviously not a completely permanent fix as there appears to be a wire breaking inside the bundle in the cord. Not sure what to do now as I don't have the soldering skills to replace all those board connections with a new tether. Perhaps I'll just have to be careful with the position of the tether as it goes between the tender and engine and adjust it again if it starts acting up.
