Hunka Hunka Burning Love Posted November 13, 2017 Share Posted November 13, 2017 Please please please God, let the only Gotway wheel that Marty Backe doesn't own be a good one! I've waited this long for a wheel that he doesn't buy, please let it pay off! Don't mind me - just mumbling some prayers to myself. Link to comment Share on other sites More sharing options...

Since my Mten3 failed I've been kind of bummed. So I needed to interject some new excitement into my EUC life. I pick it up personally from Jason tomorrow.

radial Posted November 14, 2017 Share Posted November 14, 2017 20 hours ago, Marty Backe said: Yeah, thanks If I get lost come reassembly time, I'm calling you (but maybe yours is still in pieces waiting for a tube?). I will video the fix. Sorry, but you have to admit you were tempting fate with all those cool Mten3 videos . Speaking of my situation, I got a package in the mail just today that should get me back on the road. I had placed several orders for innertubes. The pictures and descriptions on Alie leave a lot to be desired. One order arrived a couple of days ago, but that one was a bust. Anybody need a tube of exactly the right dimensions but with the valve oriented at right angles to the plane of the wheel? Yeah, me neither. But the tube that arrived today looks just right. 10" in diameter, 2.5" nominal width, valve correctly oriented. Here's the link if you want to order one. https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042311.0.0.6VW7Ih&orderId=87463116978632&productId=32826614144 Link to comment Share on other sites More sharing options...

The Fat Unicyclist Posted November 14, 2017 Share Posted November 14, 2017 So, to summarise the underlying theme of this thread... We should all check with Marty before buying a wheel - and if he is buying the same one at the same time then don't. Stick with that and everything should work (that is, for everyone but Marty)!

Marty Backe Posted November 19, 2017 Author Share Posted November 19, 2017 I have determined why my Mten3 failed. To summarize, Gotway designed and/or provided a battery pack that is not compatible with the power requirements of the powerful Mten3 motor. Here is the video that lays it all out followed by some photographs. As I type this I feel inclined to write the battery pack off as a total loss. Considering how much a new battery pack would cost, I may have to buy a new Mten3. Link to comment Share on other sites More sharing options...

Basically an utterly inaccessible, non-replaceable fusible link. Seems way under-engineered, even if your turnstile incident generated anomalous current load not representative of normal operations.

mezzanine Posted November 19, 2017 Share Posted November 19, 2017 Excellent job on the video breakdown @Marty Backe, the macro shots combined with the narrative of your thought process makes understanding what happened easy. I'm the last person to give electrical advice, but I'm cautiously optimistic that it's only the burnt contact that's the problem. If I had to bet, I'm guessing you'll be able to fix it and there isn't any bad cells. Would you need a spot welder to be able to fix it or could you use a normal soldering iron?

Gimlet Posted November 19, 2017 Share Posted November 19, 2017 Might be an idea to reconnect the two battery halves with an accessible replaceable fused link Marty. Link to comment Share on other sites More sharing options...
Hunka Hunka Burning Love Posted November 19, 2017 Share Posted November 19, 2017 On the positive side hopefully the nickel strip that burnt away acted as a "Gotway fuse" that may have saved your control board. If there is room in the case, I would get some flux, put some over the contacts and solder a heavy gauge wire or two across to bridge it making sure beforehand that it will fit back in properly. It's strange though why the nickel strip melted at that exact point. Does it butt up against the plastic shell somehow or was there a pinch or bend in the metal I wonder? Maybe the PCB separator board underneath in close proximity has something to do with it. Hopefully someone at Gotway knows the detailed assembly of the pack and can figure out why it failed at this point. As Gimlet mentioned, maybe it's a good spot for a fuse, but what amperage would be suitable here? When push comes to shove, something is bound to fail if a wheel is pushed beyond its operating boundaries. Better it be a repairable nickel bridge than a pricey control board?
