Car Battery Problem

Was it under the hood?

yes just I followed the battery cable, an it lead to the box If we learn from each success and

each failure, then we can improve ourselves

The first thing you need to do is measure the voltage on the battery. The OCV *open circuit voltage* for a 100% charged SLI battery will be aprox. 12.8 - 12.90 volts DC. The next thing you need to do is varify that both cables, power and ground are indeed sound in connection and fitment. Make sure there is not an open in either cable. Take your DMM and measure the resistance and the continuity of both cables with the battery disconnected from the vehicle. The ground cable should measure less than 2 ohms aprox. The (+) power cables from the battery, leading to the fused power distribution block should measure the same resistance, you will have to disconnect the other end of the power cable from the fuse block so as it measures the cable resistance and not the misc circuits attached. If both cables are indeed fine, and the battery measures fine. The next step is to remove each fuse one at a time and varify each visualy, and with a DMM to ensure they are not open. This includes all the fuses in the cabin. The next thing from there is to obtain either a Helms, Mitchel, or Auto Tek information for your model year vehicle and check each circuit affected. If you are not up to the task then you are going to have to bow out and bring it a a technician you trust, to trouble shoot the problems. Good luck EVIL Teken . . .

What does DMM stand for?
