BlueRanger,
Thanks. I had the entire charging system tested last summer when I replaced the starter/solenoid (see my posts from last August), and everything was fine. I thought batteries got weaker as you tried to start, or cycle the glowplugs, over and over. I figure I need a battery anyway, even though it is an 84 month one. I've ordered and received (27 hrs!) an ignition switch from Phil at FastLane which I'll put in this weekend. I just want to make sure I cover all the diagnostic bases and think it thru before I start pulling parts in the driveway...
