rectifier/regulator problem?

[niggalai]

so ive been busy rewiring my '77 gs550 to relocate my electronics under my new seat cowl. in doing so, i burned part of the harness and had to bring it back up to par. after it was all patched up a second time i hit the ignition and all my lights/starter motor/coils were all getting power. i went to the gas station to buy some fresh fuel to try and fire her up for the first time since march. after the tank was full i tried to turn on the bike, but watched my neutral and oil pan light dim until they turned off. i checked my fuse and found it had blown, so i replaced it. as soon as i tried to turn it on again it blew. now this electrical system had been working for over a week as i wired all the lights, and i took caution as to make sure all connections would not cause another problem to happen. could my problem be coming from a bad rectifier or regulator? is there any way to test to find out what the source of my problem is for sure? i have a multimeter but now face the problem of no power running through the bike.

any help is appreciated,
nikolai.

Sorry to say but you have a short.

Need to start at the beginning and test each circuit. Will be easier to start with those that you've repaired.

I know someone who thought they always had it right when it was reassembled . They know better now .

Go back and check your work as a starting place.

The nice thing about tracking a dead short like you are describing is that you do not need to have power to the bike. Just use your multimeter to find ~0 Ohms or use the buzzer to indicate no resistance.
You'll get there, it just takes a bit of time to recover from an Oops like you encountered.
