Hi there! My name is Xennon Yazon from the Philippines. I have a Panasonic Off Time folding bike with a mid drive motor which I bought from a Japanese surplus bike dealer. The battery which is an NKY201B02 doesn't work anymore so I tried connecting a different battery following some of the guides on this forum. When I first connected the battery to the positive and negative leads, there was a spark on the terminals. After that, no more sparks which lead me to believe that I blew the fuse. I have since removed the motor assembly but I cannot seem to locate the fuse. I suppose that there are fuses because it says so on the round translucent plastic pouch which covers the wiring connectors. This round plastic pouch is inside what is supposed to be the bike's bottom bracket which is an unused component of the bike. On the plastic case it say 20A beside a fuse icon and another fuse icon says 0.5A. So most probably there are 2 fuses. Does anybody know the fuse location?
I have looked at FLECCs page here, http://www.flecc.uk/p/motorunit1.html, but I don't see any fuses mentioned or in any of the pictures.
Thanks by the way to FLECC for the informative pages about the Panasonic motors. It has a wealth of information!!!
If anyone can point me in the right direction, it would be much appreciated.
All the Best,
Xennon

Hi Xenon, there is no fuse in the Panasonic crank motors but their batteries have fuses. Their original ones that used NiMh batteries had two battery fuses are inside the battery casing as shown here in a photo from my recelling page for the old unit:



But your model was sold with a small lithium battery and I don't know where the fuses were in that.

However, if you connected the other battery correctly and it arced, you may have blown that battery's internal fuses, so you'll need to open it up to check for its fuses.
