A friend of mine bought a 1988 georgieboy MH that wasn't charging so he replaced the alternator and it still is not charging.he said there is only one red wire attached to the alternator which is the power wire from the battery,he said it looks like some wires may have been cut,what color wires should be attached to the back of the alternator to make it charge? does anyone have a wiring diagram of the charging system? Thanks!
