I am having a problem with the charging system. It is providing enough power for it to run, but not to charge the battery. I have replaced the stator and voltage reglator. It appears that I am getting plenty of power from the alternator, but I get less than 1/2 volt increase at 4,000 rpm at the battery so the battery won't charge. I unnderstand that I should be getting around 14v at 4K, but I only get 12v. Oh, I also replaced the battery.
