should be getting a mate to build up the bash plate soon, CAD work finished..
I might have mentioned above that I replaced the FETS on the BBS02 controller without success I thought I would post here.. the symptom was that it ran on throttle for around 5 seconds, then when I closed the throttle, the motor kept spinning. I pedalled backwards or something to get it to stop, and once it stopped it was dead, wouldn't spin again. this time when I pulled out the FETs I decided to measure them all, and discovered that it was only the high side that was cactus.
So this is the photo of the controller...
Going from memory (it's been a week or so since I looked at it) there is a single FET on the 'high' side ( the one on the left), and parallel FETs on the low side. It's the high side FET that keeps blowing, which is on the left.
I thought perhaps there was a get resistor missing, and it was a floating gate, from the looks there are no components missing except the pads on the far right of the pic. . Can any guru's suggest why perhaps a high side FET might keep blowing? I should probably measure gate resistances. etc etc. maybe there's an issue with the driver and it's feeding 48V to the gate.. don't know..
