i have been wondering the same thing atomarc, could the charging issue be related to this starter issue or vise versa?
i had the old starter switch off a couple of weeks ago when i was cleanning all the cable, wire and contact points for anything related to the charging system. the brass contacts inside the unit looked a little worn but they cleaned up pretty well so i wasn't all that worried about it. i think i'll just replace it since everything else is brand new in the system.
longbox, the linkage is in good shape. very little play and thanks to a strategic oil leak, the pivots are well lubed. thanks for the suggestions anyway!
all i know is that as much as i like working on my truck, i'm about ready to be done with electrical stuff for a while.
