Hi, I need some help, I have a 318 S.N. 42025- and am having charging system issues. I found a poor connection coming out of the voltage regulator Now it is charging, but the previous owner ran a wire straight out of the 12 volt wire from the voltage regulator straight to the battery. I know this is not correct. does anybody out there have a copy of the wiring diagram? I would like to put the wiring back to factory. any help would be appreciated. thanks.
