Is it the reg rec in the Alternator gone.... have you run a multi meter over it... if so what are the results???

I'd bet your battery is shagged at the very least.

Beg, borrow, get a battery that is charged up, pop it in and start the engine.
Put a multimeter across the terminals.
If it is under 13 volts then the Alternator is U/S or the sense wire/plug is U/S
If it is high 13 to low 14 then the Alternaotr is OK and your original Battery is shagged
