I'm having one heck of a time with starters! I've got a '93 Ford Aerostar.
I've probably put 4 or 5 starters in it in the past 3 years. The most
recent one lasted four months. I'm starting to think I need to carry a
spare starter and jackstands in the back with this thing.
I can't figure out if I'm jinxed, if I've got some underlying problem
causing this, or if rebuilt Ford starters just plain stink. I've bought
them from Napa, from Ford, and a reputable local parts shop, all with the
Electrically, everything seems to be fine. The starter relay seems to work
correctly, battery voltage is fine, connections seem fine. When I remove
the starters, I don't see any signs of abnormal wear on the teeth.
The failure modes for the starters have varied. Two of them had problems
with throwing out the drive gear; the mechanism seemed to be jammed.
If any of you folks have any ideas, advice, or suggestions, I'd sure
appreciate hearing from you.
