the three wire plug that connects the stator to the harness get rid of it (its probably melted ) and hard solder the three wires, do the same where the regulator plugs in to the harness, and then the on the neg side of the batt ( this is probably the main problem ) there is a grounded spade connector, get rid of the spade connector and bolt the wire right to the neg side of the batt
and i garantee youll be putting out 14volts
