Low Voltage at Idle

["dsscid" <shain@xxxx>]

Hello Everyone,

Recently (probably ever since i got the new alternator) i have been 
experiancing low voltage when i'm at an idle. The volatge at idle 
has been roughly around 8-10 volts, and as soon as i accelerate it 
jumps to to 12-14 volts depending on what is on in my car. I took 
the car to the place made sure everything was on ok, he insisted 
that I check the connections. So every ground connection, power 
connection etc. on my car has been removed, cleaned, and replaced as 
needed. Still low power at idle. I tightened the belt, check the 
dash light and everything seems well. I am reading little over 12v 
at the battery (engine off) and between 10-12 volts at the alternator 
when running. Anyone have any ideas. I just spent a few hours today 
running an additional ground wire from the battery to the frame in 
the rear (just in case). BTW, i have a brand new ac/delco 140 amp 
alternator.
