    Crystalyte 72V problems ... new setup questions

    I will open the motor again these days and look if the axle and bearings are right and if I put them together right the last time I opened it. I just bought a 18FET 4115 controller from Lyen and will raise to 30S Lipo. Is there any recommendation for a BMS? I didn't use one up until now but...

    HE Cabling: Micro B USB Connectors

    Just bought myself such an extension micro-b cable and it only has 4 wires. Just wanted to let you know so you don't buy anything wrong. It looks the same as in the pictures above and the description said 5-pole. Andy

    So I replaced the FETs again and those seem fine. Something else blew and I don't know what. Don't really care anymore though. I just want a new and reliable controller. Still figuring out which one would fit best for me. And thank you for the links and video NeilP but I don't really have...

    Been really busy the last few days so I just saw your posts. @wineboyrider: My dad lives near Koblenz. Great coincidence. :) @NeilP: Thank you for the ideas. Will check that out now. @all: So my bike was working pretty good the last few days and I have been riding it daily. The weather is...

    Crystalyte 72V problems ... new setup questions

    Thank you for your suggestion but I actually did mark everything before opening it. Should all be as it was before. The rear wheel is still wiggling while turning but I did manage to set my brakes in such a way they won't scratch anymore. Not getting rid of the wiggling problem, I know, which...

    Crystalyte 72V problems ... new setup questions

    Like I said the problem is resolved. One of the mosfets I replaced was also causing a short and after changing the mosfet pair a second time everything is running now. All I need to do now in order to get on the street again is change the cold weather outside and find out how in the heck I can...

    Just a second before I got totally crazy I thought I could use 2 more of those mosfets I ordered. So I got rid of the newly installed ones and installed another pair. And now it's all working properly. So somehow the short was within the old mosfets and in one of the new ones too. Thanks alot...

    Thank you for your answer. Well I did actually try to examine if anything is shorted but I can't seem to find out what. The screws are isolated and even without them it is shorted.

    Crystalyte 72V problems ... new setup questions

    I'm not invisible am I? Little weird that I don't get any answers. I did some researching although this is not very easy as most of the controller related threads and wiki pages are outdated. So I figured the controllers from methods and Lyen are good but they are not selling right now. Or are...

    Crystalyte 72V problems ... new setup questions

    Ok. Seems a little unsolvable. So any recommendations for a new controller with my MagicPie? 20" casted. I would need max performance with my 20S battery pack which I could raise to 25S or 30S if this motor is capable to handle it. Only connections I would need are: Power (obviously)...

    Exchanged the 2 high side mosfets from the green phase. Guess I wasn't lucky. My measurements after the installation: black on pwr vs phase blue 481 green 005 yellow 483 red on pwr vs phase blue off scale green 006 yellow off scale black on ground vs phase blue off scale green off scale...

    Crystalyte 72V problems ... new setup questions

    So I figure I have to change the 2 high side Mosfets from the green phase wire? Just ordered 10 of the 4310Z ones. Any ideas about the hot resistors? Is that normal or does it have to do with the malfunctioning mosfet and will go away after the exchange. Andy

    Thanks alot for your help. It is almost 90°F over here and it's about time I figure out the problem with this damn bike. :) So here are 2 pics for you. I just figured the marked resistors get really hot. Is that normal? On the other pic I just wanted to clarify what setting I used to...

    Hi there, since a few weeks my bike is not moving an inch and now I got myself to try and repair it. I measured a lot and opened the motor case of my Goldenmotor Casted MagicPie. Inside everything seems ok. My measured data: Power 83,4V Throttle: Power: red > black: 5,21V Gas rest: 0,85V...
