mrelwood Posted June 3, 2023 Share Posted June 3, 2023 That sucks. Based on what you are saying and what the EUCw shows, you didn’t do anything wrong. The wheel was barely getting out of the newborn test phase, but I guess it just had an unexplained issue that probably destroyed the controller since it doesn’t turn on. You didn’t mention the motor being stiff when powered off, which would indicate a fried mosfet. I guess this was just a different kind of bad luck. I hope you bought it from a reputable seller that respects the warranty. Quote Link to comment Share on other sites More sharing options...
alcatraz Posted June 5, 2023 Share Posted June 5, 2023 My msx84 did a similar thing on a hot summer day. I don't know for sure but I BELIEVE it was a mosfet that hadn't been properly bolted down into the heatsink. I got my board fixed, and then I loctited all the mosfets down properly. Haven't had a problem since. Did 1000km on the repaired board. I couldn't see damage on the control board by just removing the side cover. It had to be separated from the heatsink to expose the obvious blown mosfet. The damage was big, even though it was a low speed failure. I also added extra cooling to the wheel by adding two more fans. The blown mosfet(s) was at the end of the row, farthest away from the fan. 1 Quote Link to comment Share on other sites More sharing options...
zaft Posted June 6, 2023 Share Posted June 6, 2023 Does your RS19 have a fuse? Quote Link to comment Share on other sites More sharing options...
Kamen Rider Posted June 6, 2023 Author Share Posted June 6, 2023 Opened up the RS, one of the XT60 battery connectors looks burnt. I did contact retailer for warranty Photos here: https://imgur.com/a/5I5z6pj Quote Link to comment Share on other sites More sharing options...
MetricUSA Posted June 6, 2023 Share Posted June 6, 2023 (edited) Oh too bad you didn't do the screen shot of the graft... The stupid ks app would delete all data as soon as the Bluetooth connection is disconnected, unlike EVW app....

alcatraz Posted June 12, 2023 Share Posted June 12, 2023 (edited) Which XT60 connector was it? There are a couple throughout the wheel. Did it short circuit? Sometimes cables are burned but functional. Edited June 12, 2023 by alcatraz Quote Link to comment Share on other sites More sharing options...

alcatraz Posted June 14, 2023 Share Posted June 14, 2023 Wow. I wonder if this is perhaps a quality issue with the connector. Either that it has corroded (contamination?) or that the tolerances weren't that great. The pin didn't expand enough in the sleeve, resulting in high resistance. 1 Quote Link to comment Share on other sites More sharing options...
