When I start my 2001 the volt meter reads 10+/- at idle then drops to 5+/- at about 50mph. This began the same time my OD stopped working. The truck starts and runs fine otherwise. I replaced the original batteries(load tested marginal) and the alternator tested fine(off the truck,not on it).
Are these problems related? Do I have seperate headaches?
