Continuing Voltage Problem revised

[Joe Palatinus <jpalatinus@xxxx>]

Ok here is the deal, This car has a grady 105 amp delco alternator in it.
THe belt is the same tension as it is in my other D. WHen I start up I get
13 volts exactly on my volt meter, and if I measere the Voltage at the jump
terminals with engine runnign I get 14.0Volts. If I let the cooling fans
come on, I get 13.5 volts, and if I have the A/c compressor on I get 11.5v
(this is with engine running) IT should be alot more than this I know, any
ideas on what to try to fix this?
THanks
