charging system problems

ok here's my deal. my charging system is dowwn.. as in not working properly. the person o got my bike from checked the stator,RR and battery and they all checked out fine. he said its a shorted wire between the regulator and harness. that's as far as he got before he got too busy to work on her anymore. so I got a good deal. anyways my charging system is only doing 12.94volts @ 4000rpms.. well my battery finally went dead. after 430miles of riding. now if I jump start her she runs fine under her own power but not charging worth a dink. my first mechanic threw his back out so can't help me. my backup guy works too much and is about reliable as the lead singer of Stone Temple Pilots around a big batch of heroine. my dads an electritian but 2 states away. so I have to do this on my own. its been awhile since I checked electrical currents (used to help my dad) so can someone point me in the right directions. like what voltage and what wires I should be testing and how. once I get pointed in the right direction hopefully it will all come back to me. thanks

Well you will need to start by purchasing a good Volt meter if you don't already have one and then download this PDF file and then its a cake walk from there.

wow so I followed the wires especially hearing about wet battery overflow problems. sure enough acid leaked all down the negative side of the battery on my regulator. so my wire connections were naasty. including some insulation melted off. I have temp covered the patches with tape..uggh I hate doing that.. jumped the bike and she is only giving me 12v at 5000rpms. but she runs clean and all lights bright on her own. my battery is drained to 9.7v so I have it on a charger for the day to fully charge it to try geetting a new reading off it. I was told it doesn't matter how dead the battery is..if she is running on her own even without the battery it should still read almost 14v. is this true. I want to get this problem fixed by memorial weekend.
