My 87 f-350 has a 6.9 turbo in it an every morning it takes about 3 attemps to get it to turn over. i have two brand new batteries and a new alternator. starte seems good. however the connections on my glowplugs seem to have some deterirorating insulation. and the are also a peg style rather than a tab style. Any Ideas and or information from those with more knowledge would be great.
