Good afternoon, Newbie to this site. We have inherited a 2007 GMC Sierra 1500 from a uncle who has passed away. It has 76000 miles on it and has been garage kept. Upon receiving it I had it looked over by Goodyear service center since I was concerned about the brakes. They found nothing wrong but sold me services that I really didn’t need....my fault there. The dealer found lots of problems with the brakes at a cost of 2500.00. They now work fine. The reason for that intro is I’m wondering if Goodyear service did something to my truck, some type of sabotage, like they did to me 20 years ago with some radiator hoses, so last night I went to move the truck to use another vehicle, it had no power, no lights of any kind, no instrument panel. So I trickle charged it all night. Come this morning the charger light was green so I tried to start it, again, no power. I tried jumping it with a electrical starter that I had bought my uncle for times like this. It would not jump, I tried that machines trickle feature and it sounded and flashed like a turn signal...tick....tick...tick, so I pulled the battery and had it tested. It had 9 volts and the service tech said things didn’t look right, so I bought a new battery. Now we come to the good part. Placed the new battery in, made sure it was clamped down, the terminals were protected with a battery spray, everything looked good and when I hooked up the terminals the horn would blare and the lights would flash causing me to jump. I tried postive first and then negative first, I checked fuses, I checked the grounds that I could find, all in a 100+ degree day. So I figure it electrical but not sure how to track it down. The vehicle is stock and has never had a problem like this before. I have read that changing out the neg. battery cable might work, but this seems a bit different. I still think it might be sabotage for more business from Goodyear, but I hope not. Any ideas on where to start looking or things to check to provide more clues? Thanks to all.
