The last time I used my charger there was an arc and it blew the fuse in my battery. Fuse has been successful replaced and I used a spare charger to charge the bike. I am a little nervous about using that charger again. Use it or buy a new one?

Thanks @JiminPT. I used the awl, changed the fuse and the battery is now fully charged.

I need to change the fuse on my Rad Rover. I have watched the video below. Mine does not have the rubber easy to remover cover. The  video mentions using an awl but doesnt say what to do with it. Mine looks like the awl version (solid black plastic). Am I basically using the awl to carve out the black plastic? Feels weird to be cutting out a piece of the battery cover.
