As I was saying on another thread I needed a new transistor and diode for my bike controller after breaking the pins on 2 of them, and then after one transistor jammed on.

I just soldered a new of each on my controller and cautiously turned my bike's ignition key while holding the power wheel off the ground in case I got a jammed on situation again. So far so good, nothing exploded on the board, and neither was the motor running for no reason. Next step was to try and ride it, and indeed the assistance kicked in, then I stopped to see if it would jam on again as was the case the previous time, but as I stopped pedaling the motor also stopped (as should be the case). So I rode for a while, stopping and touching the heatsinks to make sure they weren't getting hot.

Well I just got new batteries yesterday, fixed my controller today, and basically feel like I finally have a brand new e bike, I really was getting down with all the endless problems I was having. In any case I'm not expecting my luck to last too long either just not to be dissapointed if something fails.

I also just have the controller wrapped in electric tape (except heatsinks) taped onto my bike frame, I don't even want to risk putting it in a case because that's exactly how I broke it before. I'll just have to remember to not power it on in the rain as it's not water tight. I may eventually put it in a box, this time knowing to be very careful with those tiny transistor pins with huge heatsinks on them.

If I put it in a plastic box will it overheat if there's no air circulation around the heatsinks?

Thanks

Glad to hear that you're mobile again aab1.

As for putting it in a box, see how hot the heatsinks get at present, if they only get slightly warm when working hard they should be ok in a box.
