Marty Backe Posted July 18, 2017 Share Posted July 18, 2017 I had a hard time deciding what to label this post. Hopefully I captured the proper spirit of the information I'm providing here. Although this post is specific to my ACM experience, the MSuper and Monster uses the same hardware and unskilled Gotway labor, so I think it applies there to. Do you think it's a stretch to say that it applies to all Gotway wheels Yesterday I reported that I was not able to charge my ACM I partially opened it to troubleshoot and eventually determined that one of the two wires going to the charge port was loose. Wiggle it just right and I could charge the wheel. So guess what I get to do? Yep, tear down the ACM So here's my ACM on the bench again. Doesn't it look pretty? What I'm about to describe will not be a surprise to any of you Gotway lovers out there . At this point I take it all in stride and laugh. If only these wheels weren't the adrenaline machines that they are I'd have other options. I had to peel away the standard hot glue that is the Gotway adhesive of choice and then the lose wire simply fell away. Hmmm. I grabbed my 100mm Canon macro lens and took a couple pictures for you folks. @Rehab1 was interested in some pics and @Jason McNeil might also be interested because of the Fast Charger that you provide. First is the wire that goes into the solder socket of the charge port. A nice looking cold solder joint that made zero bond with the charge port socket. And here is the charge port. Notice all the beautiful solder in there? Oh wait, yeah, there is none You have to love Gotway workmanship and quality control. I know, I'm rehashing old news, but allow me some laughs at their expense for the inconvenience that they put me through Are we really to believe that the motor bullet connectors don't fall prey to the same crappy workmanship, even if only on Mondays? For those who aren't familiar with the background, the bullet connectors require the same soldering capability that is so aptly demonstrated here. I'm happy with my choice to cut out the connectors and solder everything. It's all blurring together in my mind - maybe the motor connectors are crimped now? Yeah, I think so. Good news, because this is just another example of why Gotway employees should not be allowed near a soldering iron So clearly the hot glue was maintaining a mechanical connection between the connector and the wire. After six or so months it finally gave out. Because of the mess of removing hot glue (why in Gods name is hot glue required anywhere in a wheel instead of mechanical fasteners?) I opted to not touch the other wire. I'll cross my fingers that the person got that one right. It feels solid for whatever that's worth. The next point is well known to many of you I'm sure but I'll state it here again. The wire going to the charge port and to all the batteries is 20 gauge wire. I counted 18 strands. Solid (1 strand) 20 gauge wire is good for ~6 amps. 18 strand wire is good for ~3 to 4 amps. I ever so briefly contemplated replacing the wiring but that would entail a huge amount of work, including opening each battery. I don't think it's wise to push 5 amps (EWheels 5 amp charger) through these wires. Not for extended periods anyway. I've been using the Fast Charger at the 4 amp setting and I'll continue to use that. 5 amps would probably be OK, but we're starting to operate at the margins now. I'll stay a little on the conservative side and stick with 4 amps max. I don't think there's much more for me to learn about the ACM, so please Gotway Gods, leave me alone for awhile EDIT: I forgot to mention that my fix was to properly solder the wire to the charge port.
