And yes, the way I read it any buyers from Ali for instance should get their replacement boards from their seller and will have to change them themselves (as should be expected). This is somewhat clarified by Kebye in a subsequent comment (quoted below), although it doesn't explicitly say that these will be free of charge, but that's my current expectation. Will see how it plays out with my seller. Just got word back from my Ali seller just now (Wheel Tech Store), and it seems they will provide a new board for me. They said as much previously in communication, but that depending on Gotway actually officially providing replacement boards for the Nikola 84V which Gotway has now agreed to. They said there's a wait time since Gotway has a backlog to provide all the sellers with new boards, which is reasonable, but so far the whole thing checks out. Not a problem for me per se as I'll personally happily ride my verified glue-free Nikola in the meantime without any worries, but it's still nice to see that the recall and action also applies to any wheel purchased over AliExpress or other sellers (and I certainly don't want to begrudge myself of these beefier MOSFETs or an extra PCB in any case no matter of the actual consequences ). So far, it seems a welcome change from my last V10F purchase last summer where Inmotion globally not only not responded, but when they did it was to point out that they might disable the Inmotion app for me since since the wheel was bought outside of ordinary sales channels. I don't really have any beef in this as I I'll happily buy the best wheel available from any manufacturer actually catering to my geographical position, but in my personal experience so far Gotway > InMotion when it comes to issue handling, at least for us non-local shoppers. Will keep you all posted with any updates. and out of interest would love to hear the experiences of any other buyers with different sellers!

As am I, and 1+ so far for their handling so far (one has to understand that we're here in the forum is on the bleeding edge in one sense). I'm not sure all Americans understand this, but to borrow a parallel from the mobile phone world here in Europe we don't really have the same concepts of carriers, and if I buy a phone from a manufacturer with faults I hold that manufacturer responsible (and in a lesser sense the carrier, if any, even though if there's a problem and i bought it from a carrier I'd expect the carrier to handle it for me if applicable (never happened so far since I've personally haven't bought a phone via a carrier..)). Regardless, any manufacturer is expected to fend for itself, and to accept the consequences of any fault manufacturing. Thus I don't care much about sales channels or whatever, but just that manufacturers stand behind their product regardless of sales channels and making things right for their customers.

AtlasP Posted July 2, 2019 Share Posted July 2, 2019 (edited) 10 hours ago, Marty Backe said: The most important part is to disconnect the battery connector first and then turn on the wheel to discharge the capacitors. This makes total sense and yet I'd never heard it before in the context of EUC's specifically. Does this apply to all brands or only certain ones (perhaps based on their particular board designs)? When changing a v8 tire recently we had to disconnect the battery and then disconnect the motor leads from the control board and no-one said anything about turning the wheel on first after disconnecting the battery but before disconnecting the motor leads.. Edit: Oh I completely understand why. I was just so focused on following the directions for the disassembly exactly and they didn't include that as a step and so it didn't occur to me in the moment. Noted for the future. Edited July 2, 2019 by AtlasP 1 Quote Link to comment Share on other sites More sharing options...

It's a precaution. You'll see that when the battery is disconnected you can actually turn on the wheel (it'll beep and lights flash) but only for a second or so as the energy from the capacitors is drained. If you don't do this there's a slight chance that you could shock yourself or damage the control board by accidentally shorting some connections by touching with a screwdriver, etc. It's standard safety practice when working with electronics. I imagine this would apply to all EUCs Edited July 2, 2019 by Marty Backe 6 Quote Link to comment Share on other sites More sharing options...

Probably all brands. The boards connect directly to the batteries, the power switch only gives a signal somewhere (probably either to wake up the MCU or enable step-down converter powering the MCU and other low-voltage stuff) to start things up, the the board's powered all the time (at least the input caps are charged if nothing else) when the batteries are connected, but might only be in "sleep mode" while "off". If the power was actually routed directly through the switch, it would be huge, the switches can't handle such currents as the wheels use when riding. Discharging the caps is a good idea, the voltages are high enough to do serious damage if shorted, or in right conditions, give a really good shock, possibly stopping your heart if passing through it.

Popular Post Marty Backe Posted July 2, 2019 Author Popular Post Share Posted July 2, 2019 (edited) New Control Board Is In The House Just received the new board. I can tell you that this is a completely new board. They didn't just put new MOSFETs in (not that they could have fit on the old board), but in the details, everything is different. The thermal transfer sheet does not have self-adhesive, but it's one large sheet that means there's no need for glue when assembling the unit. On a more frustrating level (which we've seen in the past - nothing new here), the connectors are different. Actually, not different connectors (that would be really bad) but different locations. Of course I documented my existing board, but it's quite a bit different. Fortunately I happened to come across this picture that Gotway posted to Facebook. With this information and tracing the wires in the wheel, I should be able to figure out what connector goes where. Let's hope maybe in 10-years we'll have proper documentation. It's like you go to your car dealer to get a replacement door switch and all they can sell you is one that looks similar but has different pin-outs, etc. Edited July 2, 2019 by Marty Backe 8 6 Quote Link to comment Share on other sites More sharing options...

Popular Post Marty Backe Posted July 3, 2019 Author Popular Post Share Posted July 3, 2019 (edited) New Board Is A Fail - Fixed This is extremely frustrating and makes me pissed at Gotway all over again As I intimated in my previous post, the board configuration is different. Well, the wiring harness is so different that it's incompatible with this board!!! You can imagine my frustration as I excitedly put the wheel back together and have this result. Sure the wheel balances and almost everything appears to work. But the headlamp is always on. On the old board, one wire attached to a connector that went into the speaker module (what's up with that?). And the other went directly to the control board. Now, both wires to the fan are pre-installed on the control board. The connector from the speaker module? Just handing there because there's nothing to connect to. On the circuit diagram above, there's a connector for the light. I don't have any unused wires to plug into that. I'll continue poking around, but wouldn't you think that Gotway would know they made incompatible changes and offer advice??? I'll update this post if I can figure something out, otherwise it's a plea for help to @Jason McNeil Fix After tugging and probing I took my best guess at the light connector and moved it to the Light Connector shown in the picture. Now everything is working. Still leaves one of the identified connectors (USB/Tail light/etc) un-populated, and that wire from the speaker module that used to go to the fan is still dangling. But it works. Jason is going to have a fun time documenting this for the people that get to do this. Oh, and all of those gray plastic covers that hide the shell screws - they aren't all the same size. So keep track of those as you remove them to prevent you having to spend 10-minutes finding the right cover for each screw So I'm calm again Overheat hill test tomorrow morning.

Marty Backe Posted July 3, 2019 Author Share Posted July 3, 2019 (edited) The Wheel Is Working, but ... The fan never turns on. So instead of running at a normal ~40-degrees Celsius, the board is hovering at ~60-degrees Celsius. The fan on this new board is already connected to the control board so there's nothing for me to do. I can't help but wonder if the now unused dangling connector from the sound module is still supposed to be connected to the control board, but Gotway neglected to provide the additional wiring harness cabling. I have a question into @Jason McNeil. I can't imagine why one lead of the fan on the old board was going into the sound module. But it's nice to have a running Nikola again. I took it for a ~10-mile night ride around town. Debating whether to still take it to Overheat hill tomorrow ... 1 hour ago, Dzlchef said: That sucks, but glad you figured out how to make it work.

beast@tanagra Posted July 3, 2019 Share Posted July 3, 2019 Am I the only one wondering how they produced a new control board so quickly? How long does a board take to design, produce, test and ship? It's Gotway, so I'll presume they're leaving step 3 to Marty, but doesn't this board have to be from some other product? Hopefully a 100v Nikola, but perhaps a different wheel altogether, one wired very differently? 2 1 Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted July 3, 2019 Share Posted July 3, 2019 @Marty Backe No fan, no test!

Hopefully a 100v Nikola, but perhaps a different wheel altogether, one wired very differently? The 100V Nikola was going to have a bigger mosfet board from the start, presumably this one. It is also very similar to the MSX board (at least on first look). Someone mentioned it also doesn't look too complex compared to the KS boards (which also manage the batteries in some way). So Gotway can probably pump out "new" boards very fast by just changing the firmware and maybe doing some simple hardware change (if at all). They're very iterative there. I wouldn't see this quick change as a bad sign *knock on wood*. I'd bet it's just a 100V Nikola board with different firmware. 2 1 Quote Link to comment Share on other sites More sharing options...
