K5 Won\'t Start....Help! Went to start my 86 K5 and got nothing. No clicking noise, nothing. Head lights don't work, auto door locks don't work, dome light doesn't work. Checked voltage on battey and it was 12.5, didn't check while I was cranking though. Tried to jump it but that didn't work. Banged on the starter and that didn't work. Checked fuses under dash and none were blown. Battery is 2 yrs old (Die Hard Gold), starter is about a year old. If the starter was bad, I should still get power to the headlights right? If the battery was bad, it wouldn't be showing 12.5 volts, right? Could it be the alternator? Are there any other fuses I need to be checking? How can I narrow this down? What's even worse it that it's stuck in the underground garage at my work. Why couldn't this happen when it was in the garage at home!!!!
