Those starter bolts are sometimes so tight and resistant to release. I wondered if the high current draw and possible the starter using a partial interface with the screws as ground. Created that situation.


In any event I have great interest in always taking care to get the top bolt's 10 mm hex socket both well in and use a very hard type of tool. Sometimes from the force I have had to apply. It is amazing the bolt did not break or round out. This on the 5 cylinder 123s of course.
