I'm a little dense, how did having a bad tooth on the drive end make the distributor "increse speed"? Since on one tooth (on a helical cut gear) is ever carrying the whole load, how did it affect anythign unless it was totally missing? Even then I can't see how it affected voltage through the module. If it was missing so much gear that it was affecting the electronics, how did it manage not to jump timing by one tooth for every rotation of the distributor? There's something funny here and I suspect there was something else wrong with your distributor.Originally posted by UNCLE BOB
Yes the dist. gear on bottom of shaft,When it hit the bad spot it increased speed from missing the chipped spot,inturn increasing the juice and burning the module until it could'nt take anymore and blew.which was about every week and a half. Twice.Until my buddy said "let's change the dist." And there it was.
