Electrical short?

So I have a 76 gl1000 and last year I got caught in the rain for 10 minutes and then shut bike down as soon as i got in garage. The next day i went to start it and the 5 amp fuse just below the top 10 amp blew.. so I replace it and blew agian..
Forward to this year.. i went out and did a continuity test with no fuse... and still have continuity .. to both sides. Looking like maybe the power for blinkers and horn may have melted somewhere in harness it the only thing I see on diagram in the same area.. any thoughts or tips?

My first question.What doesn't work on the bike?
Park lights?Horn? Headlight?etc.
I can track from this info.

My apology. I forgot to say.. well actually nothing works as soon as i turn the key on it pops.. I tested it with continuity test and seems ok. Maybe I'm missing somthing easy

Ok..so you turn on the key and it pops the fuse..Is the headlight still on?will it crank and start?Does the brake light work?
All with the popped fuse?
Or is the bike completely dead.

As I look.A blown 5 amp fuse would leave the bike still able to run.

So I'll post a pic of what I'm talking about. The red circles are points that have continuity. All connect to one another no matter how I tested it..not good... also what really got me was the 5 amp fuse.. /second from top/.. when I took fuse out it still had continuity

No parking lights. No horn. no headlight. None work at this moment. When I get home tonight I'll look at it more and try to get more info than just the vague info I have provided so far

Hello . I am haveing the same problem with my 77 i have turn signals but the gage temp light fuze the same 5 amp keeps blowing . And no headlight ether . It had a wind jammer ferring that i removed and the scotch locks as well. I am haveing a hell of a time finding the problem. It acts like a dead short popping the fuse instantly when key on.

So i have found my problem...i found my starter button broke inside and shorted out.. i did the relay mod.. and now i can get power without fuse popping... but no starter..... so i double checked My starter solenoid. And bingo... it was bad... so now i have the new one in and it runs again...

So i found the starter button was shorting..
