87 F250 Alternator issue??
I have a 87 f250 thats been on the fritz as of late. Im sure that it must be the alternator now but looking for another opinion.
After putting the truck on a battery charger for 5-10 minutes it starts like a dream. The charge gauge however does not move at all and the battery light stays on untill the truck eventually drains the batterys and all electric functions(radio light etc) stop, but the truck still runs fine till shut off then obviously does not start.
I could see if this was an old alternator. But it was just changed approx 8-10 months ago, and has maybe seen at the absolute most 1500 miles. Have been told by a few people that it could possibly be a blown diode. Anyone experience problems like this before, or know where to get a diode kit or how to change one?
