First thing is to make shure you have good grounds between the engine & frame & frame to body. If it is an external regulator make shure there is a ground wire on the regulator base as they are mounted on rubber grommets. Then take a hard look at the voltage regulator. A defective battery could cause this problem. It is the balast for the system. What part of Mo. are you in.
