I accidently hook my battery charger to the wrong posts (rusty clamps, faded colors). It was connected for approx 3 seconds that way. Now, my radio/CD wont work. EVERYTHING else works, gauges, lights, power, door locks, cruise, etc. and the radio lights up with night lighting. I've pulled fuses from under the hood and along side the dash/driver door but can't even find one stating RADIO.
Finally, I had a different radio without cassette and changed to that radio... same results. So the radio itself is not fried and apparently it's in "security" or something prior to radio. Where is the RADIO fuse?? Any other ideas?? THANKS in advance.
There is a panel on the passengers side of the car, I pulled the fuse used for OnStar because I dont use it. I didn see any labling on mine but it was the fuse located second from the top on the left side, but you have to be looking at it side ways because of the way the fuse box is orientated.
And then put it in the socket all the way to the right second from the bottom, again looking at it sideways. NOTE: My car is a 2006 Malibu LT
Thanks for reply. There is no in-line fuse behind radio but low and behold there is a 3rd fuse panel on the other side of the dash at the passenger side door. Ya think ??? It was a blown 10 amp fuse but even that one didn't say "radio", "stereo", "sound" or anything remotely close. Just had to check every fuse.

No. You could have a bad connection at the battery post. Often, the cables going to the post of the battery is not properly seated, which could cause a weak connection from your battery to your starter. Take a closer look at the base of the battery posts and your battery cable clamps and see if the cable clamps are seating at the bottom of the post, if not, lightly hit it until the cable clamps are nice a snug.
Locate the Positive cable marked with a + sign.. connect the red cable on the charger to this post.. Take the other clamp from the Batt charger and connect it to the neg Cable post Marked - or connect the negative clamp to anymetal part on the engine.
Assuming you have a battery charger. Do not plug charger in until after it is connected.
1. Open hood & locate battery.
2. Identify the positive terminal of the battery (usyally has a red cover or red marking.
The battery has side terminals (not posts like nonGM batteries)
4. Connect the + red clamp the the positive terminal wiggle it a little to get good connection.
5. Connect the negative black clamp to the engine block, a handy bracket on engine or the negative terminal on the battery. DO NOT CONNECT TO ALTERNATOR
6. Be sure connections are secure.
7. Plug in charger it should show charging. Leave it over night
8. Before disconnecting charger disconnect power to the charger.
THE FUMES OF A BATTERY ARE EXPLOSIVE DO NOT USE FLAMES NEAR BATTERY
DO NOT ALLOW SPARKS NEAR BATTERY!
check for proper ground and check to see if you accidently poped a fuse while connecting the wires.Check to see if there are any in line fuses on the radio wiring and see if they're blown.if not, hook the radio up directly to a car battery(with a fuse in line on the power side) and if it doesnt work then its a problem with the radio, if it does, its a problem with the wiring.
I suppose this is what you want to know
The battery charger has 2 leads coming off it as well as the power lead to the external power source .THE TWO LEADS WITH CLAMPS ON GO TO THE BATTERY THE RED GOES TO THE POSITIVE TERMINAL PLUS SIGN AND THE BLACK GOES TO THE NEGATIVE TERMINAL.MINUS SIGN, THE POWER LEAD PLUGS INTO THE POWER. AND THAT IS ALL THERE IS TO IT..
Dont know about security mode on the car, check your manual.
Check your battery by turning on your headlights and see if they work, if they do and work good then the battery is charged. If thats the case then it could be a security mode thing, if not a security mode thing then it could be a bad connection to the starter or a bad starter or starter relay.
Try the headlights first and see if you have juice.
If you donts check to see if you left a interior light on or your headlights, if so, recharge your battery and you should be good to go.
Do you have a battery charger? If you do, connect the red(positive) clamp on the charger (+) to the Positive (+) battery post. Then connect the black(negative) clamp on the charger (--) to the (--)(negative) battery post. Make sure these are hooked up this way, if they aren't, you can damage the car's charging system (big bucks to fix). When you are sure the charger is connected to the battery properly, plug the charger in. It would be best to let it charge overnight. You must then find out why the battery went dead, otherwise, when you go out someplace and turn the car off, you may not be able to start it up again. If it's the original battery it's time to get a new one. You can drive to a major parts store, they will check the battery and car's charging system to see what's wrong for free.Good Luck countrycurt0
