1972 CT70 Fuse Issue

I'll try to keep this brief.
After getting my 1972 CT70 running, I decided to clean up the appearance of some wiring from the stator wires to the harness/plug . I got it back together and now I can't stop burning fuses. I disconnected the harness plug and plugged it back in but the same thing keeps happening. I may have put the wrong fuse in at some point (bad eyesight). I realized it when the wires from the battery were getting super hot. Where would be a good place to start troubleshooting? And how?
FYI- engine, gas, tank, and entire wiring harness have all been removed again. Any help would be greatly appreciated!
 
Thank you for the reply, Rick. I'm not super savvy with electrical but I believe I checked all the wires from the stator (and most within the main harness). Everything seems fine and zeros out when checked with a multimeter. Can you walk me through how to check "for continuity to ground on the power wires that I touched at the stator". I'm a rookie.
All I really did prior to the issue was pull the top engine bolt (and a few other things) to drop the front of the motor down so I could untuck the wiring harnesses within the body. May have pulled a bit on the wires but not much.
 
How did you check the wires you touched? What did you check with your multimeter? Set your multimeter to continuity / ohms. Check the end of each wire with the red multimeter probe and the black lead on a suitable ground. There should be no continuity to ground on a stator wire.

You could also have a failed rectifier.

I have a multimeter and alligator clips to check for shorts to ground.
Clip one side of the alligator to ground and the other to your ground (black) lead. Then set to continuity and tap each wire to check with your positive (red) lead. If it beeps, it goes to ground. Double check wiring diagram to see if it should go to ground. If so, happy. If not, short to ground.

Reverse the alligator and clip positive to battery positive lead (no need for the battery to be wired in) to check for short to voltage.

A wiring diagram is vital. Have patience. You'll be okay. Check with YouTube University. That's how I learned.
 
Thank you, both for your insight. I will tinker with it. Was hoping it was a quick-fix... they rarely are. Ha. Just so frustrating that I had the bike running (beautifully) prior to my brilliant episode, now this. I will keep y'all updated.
