I have had that 5 amp fuse blow a couple of times, could not figure out the reason. My battery tender will just blink red looking like it was not hooked up. Mine will glow red when charging, green when charged and blink red when not hooked up.

Only reason I can figure is if I plug the tender in hot, it gets some sort of surge and blows the fuse. Once replaced it works correctly, has only happened twice since I got my trike in 2019.

The fuse for the battery tender is the 20A P&A fuse.

all the Deltran brand Battery Tenders I have ever used has an inline fuse holder with a 7.5 amp fuse installed.

My issue was the tender lead attached to the bike. It was the 20 amp accessory fuse, all is well again. It knocked out my tender lead, my amp, and my cigarette lighter that I know of. My fault, I must have messed up and blown the fuse. I also had about 6 different engine codes I had to clear. Apparently something important was unplugged when I powered up the bike, they were all related to lost comms. Thanks guys.

Curious, what were you using for a "jumper", and how was it attached to the factory tender connector?

I had a battery tender go bad last year so I cut off about 12" of the cord and exposed the wires on the cut end. So I can just plug it into my tender lead and I have a 12 volt power and ground for testing.
