2003 Volvo XC90 No electrical power
 

Hello all, I'm new to the forum and need help. Last week on wed 10/2 my wife and daughter played in the truck and left the hazard lights on until the car died. The original battery is still in the truck and it's a little old. Anyway it sat dead for a few days and then on mon. 10/7 I tried to jump start it with cables from my wifes 2000 328 BMW. I'm not getting any lights on at all, no clicking from the ignition, nothing. I moved the jump locations on both the truck and the beemer from front to back and mismatched, but the truck is not getting any power it seems.
My questions are:
1. Is the battery so dead that it won't respond at all?
2. Is there a master fuse that maybe blew?
3. Is the starter bad, but if so the dome lights or something should come on?
4. Is the ignition switch bad?
It's weird that the battery went dead, then I'm not getting nothing, but my wife and daughter were playing in it and I'm not sure what they did. In my old 1991 Honda accord, the master fuse went bad and as soon as I replaced it, the car was alive. Is it the same in the truck?
I will take any and all help. Thanks

not sure what you mean about mismatching the jump locations. you mean you didn't connect + to + and - to -? that is a very bad idea as you can ruin your alternator like that. I don't know if this car has a fusible link (basically a fuse integrated into the battery cable). if it does that is what i'd suspect. i seriously doubt it is the starter itself as that wouldn't affect radio, etc.

Thanks for the reply, no I didn't connect the cables wrong, I mean I connected directly to the batteries, then under the hood to the jump location also. Not trying to ruin the alternator at all. I will check for a fusible link when I get home. My coworker said on his Mercedes ML truck that his battery was drained so bad he had to charge it for hours before he got any power in the truck. He advised I either change the battery, or get the one that I have now charged and see what happens. I will try both these methods and see what I get.

If its completely dead you will have to leave cables on for several minutes, (20-30mins) while the working car is running. A lot of the newer cars have jumping spots, (under the hood) on them instead of the battery. Usually a post with a red cap or a cover with (+) on it, the black side of your cables just clamp to a bolt on the fender or engine on both cars.
