Wierd Pedal Assist Problem

The 'line' is not visible in your pictures. On the smaller part of the motor cable connector there is a moulded line which should only just be visible between the two arrows when the connector is fully inserted.

Does the red PAS LED always flash, even when the problem occurs?

Another thing to consider is that horrible 11 way connector. Intermittent contacts there are known to happen, and will matter.

Google has failed me for a quick link to an illustrative pic or 2 but all the Julet waterproof style plug/socket connections have a raised indicating line iirc under the arrow indicating position on the male plug aspect showing how far down the lip of the socket needs to be pushed to fully engage.

These can be difficult to push fully home and the largest 9 pin connector directly to the motor is often not completely pushed home it can lead to intermittent issues as connections are made or lost.

Trust our pal/guru ~saneagle he has a quick and direct line of pertinent Q's to diagnose problems with pin point accuracy..

I don’t understand this. Which line are we talking about? I am posting some pictures of the setup without the battery being mounted

Nicely explained here:

Got it, Thank you for the explanation! I cannot comment on how it was before because I unplugged everything before I saw the message. However, it looks as in pictures now (adding both PAS and motor connector pictures). Should I push in more? It worked for a short round around block but hard to say how it will be on actual road on Monday. Will report back

As this is Swytch gen2, a very likely culprit is the mounting bracket which known to malfunction over time and very susceptible to loose connection on vibration. The intermittent power issue that you see is a telling sign. Their gen 3 mount is much better designed.

That actually is quite possible since the commute is along a very rough path so it’s very jerky. The battery with the mount keeps bobbing up and down throughout. I cannot find a replacement mount on swytch website though. At the moment, I am going through old posts on this site to see if someone found a way to fix it (will be glad to have pointers).. thank you for the help!!

Sorry forgot to respond to this: the PAS keeps flashing even when problem occurs. Also which 11pin connector do you mean (the motor connector is 9 pin and handle mount is likely 12 pin so confused). Thank you for the help.

Does it start to judder before going off indicating poor power delivery? Anyway, the picture below shows what someone did to fix poor connectivity at the mounting bracket (copied from a post on Swytch Bike Chat).
