tail light shorted and now bike won't start

Hi there, I'm a newbie to the forum, so I'd like to say hi! I just picked up a '85 454 ltd bobber this summer and I'm having an electrical issue with it. The tail light recently fell off on a long ride (custom fender by previous owners weren't professionally done) and it cut the two wires. The two cut wires to the rear tail light touched the fender and I assume there was a short. Now the bike won't start/ ignition key turned no lights. So I started looking for a fuse box, didn't find one. Researched that the thing by my horn is a fuse box but the three fuses in there look fine. I need help with this I think. I pulled the seat off and the electricals looks really rewired (again maybe it was a amateur wire tuck). I looked at every item the wires lead to, there seems to be a:

turn signal operating unit
reserve lighting device
some sort of cylindrical relay
an igniter box
and some dead ends...

Nothing seems to be a fuse as I know it. I will update as soon as I get a voltmeter to try and discern more. Right now it's stranded at my friends so all I could do was snap these pictures




I have tried jump starting the bike - nothing happened, no power to ignition even

I read there is a main fuse that people recommend replacing, under the seat, but after removing the seat I can't seem to find anything! Does any of this make sense to those with some wiring experience? Thanks for your time if you read through all that!

I would check the battery first to make certain it is good. I would also charge it with a good smart charger & do a load test. also, make sure the battery connections are good.

Next check the fuses. Glass fuses can look good, but still be bad as a conductor can separate from an end cap, so you should test them for continuity or go ahead & get new. amazon.com might be the best place. the auto parts stores around here don't have a very good selection of glass fuses.

In the diagrams at Partzilla, the 85 EN450 only seems to have the round fuse box. it's kind of a weird. There isn't a fuse at the starter switch/solenoid. many Kawasaki models after around 1990 or so had a main blade at the starter solenoid, so I would check there as a just in case the po installed a new stater switch w blade fuse.

Fuses. If you get new fuses, you'd need a 30A AGC & two 10A AGX. AGC = 30mm or 1-1/4". AGX = 25mm or 1".
