the number one cause, but i could be something else.

do you have a multi meter?

 

Yes I do have a multi meter!

 

Set your Multimeter to read 12vdc and test between the battery terminals
first with the engine off.
It should read between 12.2 and 12.5 volts (Battery steady state voltage)
Second with Engine running:
It should read between 13.8 and 14.2 volts (Alternator Output voltage)

try replacing the ELD not real sure but I think it is in the under hood fuse box if an alternator does not fix your problem

 

What is an ELD? My alt. Seems to be putting out the right amount of juice.

 

can anyone help me with this?

 

if you don't have the tools to test the charging system, take it to sears and have them chk it out for you,,,,,but it sounds like a bad alternator

 

I had a multi meter and check it with your perimeters and it was a little over around 13.9 to 14.2 with engine running. does bog down alittle when light and things are turned on

 

ELD = Electrical Load Detector. It is normal for alt voltage to drop at idle when you load down the engine with lights and etc..........

 

Go to the dealership and get a 'brush pak' for the alternator, swing the alt up as far as it will go; disconnect the battery, remove the insulator from the alt where the battery cable connects, then the 8mm nuts on the back of the alt. the shroud will come off and you will see 2 phillips head screws holding the brush pak on.
