voltage regulator

Mon Dec 6 16:30:09 PST 2010

Getting on this thread a bit late, did you check the wire connection on the 
 alternator, and the big cable splice (that supposedly fails) in the 
passenger  foot well?  Basically run around with a meter and read voltage on 
different  places.  Should be some stuff in the archives from a few years ago.

Hey  Dave,

i charged the battery - it pulled down pretty fast - i  haven't hook it 
back up 
yet. it was the pigtail for the multifunction  sensor that had the coolant 
on it 
(because the mechanic who replaced it,  didn't tighten it enough - so 
coolant 
seeped into the pigtail  boot).

Did you try a cold start after  charging the battery for a while, might 
have also 
been that thermal switch  sitting in a puddle of coolant also?
