Electrical Issue, please help
I had to jump start my truck this morning and after I got it started it spit 2 cd's out of the stereo saying they were bad. On the way to the dump a little later the stereo just died, no power, the "ABS" light came on, sometimes when I applied the brake it pulled hard to the left. All the gauges on the dash turned off, then would come back on again, the windows wouldn't roll up. The air conditioning never failed (110 degrees today). When I was almost home the truck died for a split second then came back on again. When I got home I turned it off. Now there is now power. Whew! Is it probably the batteries? They are Energizer batteries from 09/2006. Thank you in advance. My aftermarket gauges were ok for a few minutes then they started going wacky.

Sounds to me that the batteries are shot. If you are going to have the truck sitting for a while without starting/driving it you should get a battery tender and install it. You would be amazed at the symptoms you get with dead batterys. Also if you drive it like that you may ruin the alternator too. Just check for corrosion and make sure the cables are good and tight. Other than that you may have a warranty on those batteries or they may be able to prorate them. Good luck and keep us posted.

What year is your truck, also how many miles on it. Hopefully you jumped it correctly..not to sound like a Smart a$$. If you didnt do it maybe they crossed the cables. Also if you could have someone crank it while you check voltage at the batteries. Static voltage may be ok but cranking voltage may be too low. Also check for a corroded cable at both ends if you can. That will also do some messed up stuff. Make sure the ground cable is good as well.

10.7 volts means multiple cells in the battery(ies) have completely failed, and/or your alternator is not doing its job.
Even if it is just your alternator going dead, 10.7 volts for that long has probably permanently damaged your batteries beyond saving them now.
Get new batteries in, and start the truck, it should be between 13.6 and 14.2 volts.

Yes, the batteries are in parallel as you know, so both were at 10.7 volts, sulfating the plates and damaging them. If you replace the "True" dead one, and leave the other, the other one will eventually kill the new battery

I was only reaching... I figured I might as well ask the question. I actually had to jump start it a few weeks ago when it was a really hot day. My truck sits outside in the baking sun all day long so I think it's having a toll on the batteries. I just need to limp untill Thursday (payday). Thanks for all your help.

Update: The batteries lasted this long, as long as I ran the truck everyday. This past Sunday night I started it up after it sat for 1 day and it almost didn't start. This morning it had starting issues and after I got to work I went out at lunch and it was dead. Pepboys tested them and said they were shot. $228 later I have 2 new batteries and everything is fine. Thank you everyone for your input.
