Mass failures happen when someone over tightens the lugs on the
solenoid. They do it for all thinking the tightest connection is the way
to go.
What happens is the contact twists, and then instead of transferring the
whole load only a portion of the load is transfered creating a weld.
Take apart the solenoid and you'll see what I am talking about. There is
a disk that is spring loaded and is pulled down to the lug (contact).
Twisting the lug slightly is enough to arc that spot and weld it. When
the whole contact is made at the same time there is enough suface area
to keep it from welding..
You have to keep lug from turning.
I meant to reply to the original about this.. but since you brought it
up....

I'm surprised at that many failures over that short period of time.
Something ain't right somewhere. I've never seen a failure of a cole
hersee solonoid with years of service on my winch. I'm sure you have
already, but I would check all the wiring and connections real
carefully.
