This is to give you an idea of what can happen if you over tighten the battery cable nut and turn the whole stud and contact. This is after it is all put back together and you can not see this happen.

What happens is one end (and in the case of this drawing) the long end will stick up, if it sticks up high enough ? It will stop the Plunger from traveling all the way down and it will not make contact with the other contact and guess what! YOU still have a clicker, It is Important for the Battery cable to be tight, but Can cause you to think you haven’t fixed anything if it is over tightened So this is something to watch out for.
