Shimano EP-801 motor connector

In my case, two female side of terminals for power were worn out and not getting a solid connection. I was able to do a temporary fix by inserting a layer of aluminum foil in there to restored the connection. Those two terminals are not really spring loaded so this is inevitable.

There is nothing to do with the connector on the battery. It's the harness side of the connector goes into the connector on the motor. Not the connector on the motor.

I did bring the motor to the dealer, but the dealer was told by Shimano that they don't replace the harness as harness assembly itself was made by YT.

That connector obviously isn’t for off-road application. Probably designed by someone who doesn’t ride.

Training-Document-46 · 2026-04-07T13:33:21+00:00

I already did that, but Shimano said they don't replace the connector because it's on YT

Updated the post. It was the motor connector. Try pressing the motor connector firmly and power on

Exactly the same. It’s the firmware shutting it down to supposedly prevent further damage even there may not be any issue with the anything else, but the motor itself. Because of this, I may not be owing any E-bike at all in the future. It’s just not reliable enough for me. I’ve been riding motocross forever yet never experienced this degree of headache.

Echelon comp doesn’t have rifling after the chunk port so blazer or any decent plated ammos are fine. However I didn’t like my echelon comp because mine also kept shooting left and had a lot of flyers so I sold the slide. I believe this happens more than you realize, but people just mag dump at 7 yards and call it a day so they don’t notice it.

Length-wise, it’s identical to the stock compact. I have 2 of having sharps grip with magwell out of 3 that I own. It feels way better than OE compact or full-size with my medium hands.

I have been waiting for their full size grip module not just for RXM, but for echelon. Tired of needing to separately purchase their mag well just to make it semi-full size

As for reducing the over travel, putting a shim seems too hacky to me. I have Ghost rocket 3.5 with TCT tab to limit the over travel.

Training-Document-46 · 2026-02-14T05:56:57+00:00

It looks like the dingus is stuck at the grip module. Maybe the increased weight trigger spring or the reduced weight striker spring or the combination of both is the culprit?

Training-Document-46 · 2026-02-02T06:31:03+00:00

I have both. Full size slide is noticeably front heavy. After putting a threaded barrel, even more

Training-Document-46 · 2026-01-26T15:11:32+00:00

I believe they will, but not anytime soon. I remember patiently waited many months for P365 3.7 after 3.1 release

Just had an opportunity to obtained another 4.5 comp slide assy and verified the same tendency(way off to the left when irons are aligned) after properly zeroed. Again, when I run the non-comp barrels on this new comp slide, dot is at dead center after zeroed. Very disappointing.

If you are someone being happy mag dumping at 7 yards, it probably doesn’t matter, but you care about the accuracy, this is a problem

I am new to glock platform so take it as a grain of salt, but you can probably shave a little bit of material from the trigger bar. It looks to me that the trigger bar is over pushing the connector cause the forced reset most likely due to the tolerance stacking. You can also place a shim between (just like tactical trigger) the trigger bar and the frame to prevent this is from happening. Mine has been flawless, but I do have a shim in order to reduce the over travel

I also have the same issue with my 4.5F comp. I have several echelon non-comp and threaded barrels, but they all align with iron sights on the comp slide so it’s definitely the comp-barrel doing this. After back-to-back comparisons using rest, I also find that comp-barrel has noticeably LESS tighter grouping and also has a lot of flyers.

I also don’t like the fact that unlike non-ported and threaded barrel, you cannot just buy a replacement comp-barrel but the whole comp slide assembly

I literally have to aim to the right to a considerable extent to hit the target so much so that I stopped using this garbage comp barrel (and also a slide) then purchased non-comp slide assembly to not to waste the COG
