65 barracuda not charging PLZ help

so i went through a wiring diagram and made sure i have everything wired like it supposed to be, which i do, i put a another VR on and the alternator started charging....for about 10seconds.

i was getting 9.86-10 volts FLD current coming from the VR when it was working, so now i have no power coming from the FLD side of the VR, from whats been happening ive had 2 good VR's go bad and 1 bad one out of the box.

what kills a voltage regulator?to much FLD current draw? also i did notice that my if i take a probe light and touch the neg side of the coil when running the engine dies, im wondering if i have a grounding problem somewhere or too much voltage drop somewhere in the IGN2 wiring?

to add also i was looking at my IGN switch with a multimeter and noticed when i turn the key to run pos, im getting around 12.30 volts and at the same time IGN2 is hot with about 7.85-8 volts, isnt IGN2 supposed to only get hot when you turn the key to start and is supposed to cancel IGN1 out?

ive wiggled the bulk head connectors around too and thinking maybe IGN switch is going bad and causing some of the problems, please dont give me crap guys, im trying here lol i hate wiring
