4.0 Liter, Altenator voltage out put???
Heard a belt squeel once in a while, usually on start up but sometimes while running, and noticed that when the squeel was going on the volt meter drop back to discharge and then pop back up to charge. Checked the code and have a Low Generator Voltage code flash at me. Checked the voltage with a meter and it is putting out about 14 volts when not squeeling. Can't catch it to meter it when it squeels, it's too quick and intermitant, 5 or 10 seconds at a time. I can't feel any side to side play in the pully. Belt seems to be tight enough. Could the diodes in the altenator go intermitantly like that?? Cause the altenator to discharge and drag to make the belt slip past the pully and make it squeel??? Does any one know what the altenator out put voltage should be?? What does your volt gage read normaly?? Thanks.
