Low voltage at gauge, no charge?

@67Dart273 FIXED!! Turns out the headlight problem was a bend spade terminal on the switch, I must have put the connector on cockeyed the first time it went back together and it bent the B1 terminal down, once straightened, everything works as it should :)
Thanks for all your help, it was much appreciated, beers would be in order if you were closer, cheers!!
