is there any thing I should check first before removing it?
Chevy Mechanic: Jerry Newton, Chevy Technician replied 5 months ago

How did you determine that it's not charging, is the battery light on, or did you use a multimeter, or what have you done to diagnose it?

Customer reply replied 5 months ago
the alt light is not on but it was not on last winter when the original alt stopped charging at 108,000 miles
the tow truck driver tested this one when it stopped on me
Chevy Mechanic: Jerry Newton, Chevy Technician replied 5 months ago

OK, so it ran out of electricity as you were driving, and you were stranded with a dead battery, is that the scenario?

Customer reply replied 5 months ago
the day it stopped charging I had gone out and started it to warm up.
I was in the house for quite awhile when I came out it was not running.
I put the charger on it and went ton store . I let it idle while in store came out it was not running
Chevy Mechanic: Jerry Newton, Chevy Technician replied 5 months ago

OK. Here are a few things you should test first to confirm the alternator is bad.

1. Verify the large Red wire has a good connection to the 100 amp fuse and has battery voltage at the alternator.

2. Unplug the 2 wire connector from the alternator. Verify the Pink wire will light up a sealed high beam headlight when the ignition is turned on.

3. Ground the Dark Blue wire, verify the charge light on the Instrument Panel Cluster (IPC) illuminates.

4. If all OK, replace the alternator.
