I have tried: taping them together, hot glueing them together and ziptying it right to the frame to prevent jiggle.
All have failed.
Right now, when I reconnect them and apply pressure, I can't even get the engine to turn on anymore. But the speedometer still works and that signal is sent through the engine cable too.
Recently, sometimes the engine rear wheel barely rolls when I roll the bike backwards.
There are no ebike repair stores in my city.
An alternative to ziptying to the frame or using epoxy would be to try ziptying the ends together. One slightly loose zip tie on each cable end (just below the base of the connector). Then using one or more zip ties, tie the two ends together. At least the ends won't disconnect this way, but whether or not the connection is good enough is a different story.
Could be a good temporary fix until a new cable is purchased.
