Thanks
One question though. What part of the starter is affected by heat to
need more power? Do the starter bearings get tight? Do the stator
coils somehow expand, does the rotor enlarge, do the brushes lose
contact, or what? I just can't picture how heat would affect any of
that. I know when any of these parts of a starter go bad, the starter
dies, but how can heat make it tem****arily go bad? However, I am
aware that metal expands when heated....... ????????
