Hi all,

I have a good friend who's had an E-bike for a couple of years and has been having intermittent on/off problems. He's been told that it's the 48V controller. However, it could be something else. The bike powers normally whether pedaling or not, but then the boost or power cuts out after a minute or so. This happens after every on - off cycle. I have pictures of the components, I can post later, but first, I would like to hear from someone who has experienced a similar problem and how it was resolved. Our attempts to find a replacement controller have not gone well. However, I'm thinking this may not be the problems based upon my previous life as an electronics technician. There are a lot of sensors that need to work in unison with the controller. Looking to find a schematic as well.

Thanks
