Can't Jump Start 2005
2nd attempt was tonight. I disconnected the battery cables and tried to start the car with the booster. NG. Then I used jumper cables hooked up to my C5. Nothing - let it charge 20 minutes. Nothing. The owner could not find her manual. Is there anything in the security system or other computer thing that we should try before calling the tow truck?
The original battery was replaced 6 months ago but the car has been in storage ever since.
Thanks for your inputs.
