Grounding the alternator?

[hopeitlasts]

My truck has 69k on it and I am on going on my fourth alternator. The stock one lasted until about 60k. 2nd was a reman and lasted for 6mo. 3rd was another brand of reman and lasted about 6mo. I was told that it is possible to get 2 bad reman alternator's but it seems unlikely. A friend told me to try grounding the alternator from one of the housing bolts to the frame, he said that this was a common problem of some of the Ford's he has owned in the past. Getting ready to put in alternator #4 and was wondering if anyone has heard of grounding the alternator, thanks in advance for any help.

but the ground of the motor to the frame may be bad. couldn't hurt to try it. i have heard there is a ground by the raqdiator somewhere that gets bad and needs to be redone. not sure where it is tho,haven't looked
