I am having a problem with my 80’ blazer eating starters. It just suddenly started to happen. I had not worked on the truck in weeks and then I began toasting starters. Basically, if the starter was new and I installed it would work fine, but as soon as I turned the truck off the started would never work again. All three starters were new when I installed them but when I had them tested they were all bad. I seriously doubt that I received 4 bad starters in a row. Any idea what could cause this? I think it is electrical but I have no clue what could cause it though so I am not sure were to start looking.
