The wife said when 1st putting in the key you'd hear the dinging sound, but as soon as she'd turn to crank nothing would happen. Worried it the ignition. Thought maybe the starter but no clicking sound and not sure if a bad alternator would do this.
when you turn the key nothing happens, no dash lights or radio. on 2002 Chevrolet Tahoe
I agree with wetry if the battery is ok then check alternator
TRY JUMP START.
test abttery 1st the starter
