Ya, I was researching this a little myself. That upper left F6B accessory terminal on the fuse box is only rated for 5 amps. I too, have wired a pigtail directly to my battery for connectivity for my trickle charger and 12v tire inflators. I have the pigtail fused for 15 or 20 amps (can't recall at the moment).

I run 12v tire inflators at a minimum of 10 amps.

O.P. maybe give your bike a reset. Disconnect the battery leads for a bit and then reconnect them. That could chase those gremlins away that you are experiencing. I don't think blowing the accessory terminal is going to knock out your main A and B fuses...
