battery draining down

Hello, iam new here, I just purchased my very first Camaro, it's a 2002 Convertible and every morning the battery is dead, the previous owner installed a new Alt & Battery. The car came equipped with a factory security alarm system. The previous owner had a friend install a pioneer gps/stereo/cd player (with touch screen) and did a terrible job. after doing abit of reading, my concern's are: The factory radio, is it past of the security alarm system? by removing it, could this mess up the electrical system, so when the car is turned off, it's draining the battery? while driving the car there's a "security" light on, on the dashboard. Can i disable the alarm system to see if this is the problem? or if I go to the scrape yard and picked up a factory radio, this might also make the problem go away? (this would take me a while, he cut !! the wires, just behind the plug). help or suggestion would be deeply appreciated, thankyou. Joe

Re: battery draining down

Could be several things:
New toy could be installed on BATT power rather than ACC power.
If the new toy has a clock, it is always drawing power for clock and location purposes.
OE radios have a GM security code and if power is removed from Camaro, ie, battery change, this security code must be entered so radio will play.
If no code can be found, usually on a card from GM in glovebox or with O/Manual, then a visit to any GM dealer to get code for entry, they need VIN, then security light may go off.
Also, BCM (Body Control Module) and PCM (Power Control Module) and OE radio, or any aftermarket radio draws power for memory, clock, presets, etc.

I suggest your next tool for the garage is a Harbor Freight Power-Pak so it may be hooked up to alternator BATT stud and engine ground to keep radio presets alive while battery is disconnected. Also, this helps BCM & PCM keep their 'learned' operating techniques as they learn while being driven.

I think OE radio has its own security and not tied into VATS - I think.
Others here may have more info for you.

Re: battery draining down

thanks for your reply, I hope a few others, might also help. personally i want to remove the pioneer navigator and find a factory radio, what got me think'in about it was the owners manual, if I read it correctly, if you want to change the alarm system, it has to be done thru the radio? So with the factory radio gone this could mess up the system? a faulty system could drain the battery? the security lite stays on while driving . Is it possible to remove or disable the system?

Re: battery draining down

As posted above, the Original Monsoon Stereo is its own system, as in it has nothing to do with the VATS. If you disconnect all the aftermarket electronics, your likely to stop the overnight battery drain. The VATS will not kill the battery overnight. My 2000 SS would still start after about six weeks sitting. If your not proficient at electric troubleshooting, I would take it to a good stereo shop and have them remove all the extraneous junk and just keep what you want. The original Monsoon Stereo whether it was the single CD or the Cassette Deck could control the 12 Disk Remote CD Changer which would have been located in the left rear of the Hatch Area. If your car did not come with the disk changer, the wiring harness is still there, prewired. Its probably going to be difficult to locate all the original parts, but its possible if you get a good shop that knows their stuff to use what you have. Good Luck.

Re: battery draining down

Thanks for your help, the CD changer is in the trunk, as far as the pioneer navigation/stereo, is all thats added and I unplugged that on Wednesday, the car started fine on Thursday, but was dead on Friday. I talked to the woman who owned it, it was her son that had the rims painted red and installed the Pioneer system, she then started having battery issues and the security light in the dashboard came on and stays on, up until then, she hasnt had a problem with the car, she also had mentioned that when she'd use the clicker to lock the car, the car was dead in the morning, yet if she used the key to lock the car, the car was fine and would start up the next morning, this all started after the aftermarket radio was crappie installed I also asked about the factory radio, do you control/set/change security alarm modes though the radio? if so, doesnt that mean the security system runs through the factory radio? it sounds like it,to me, so if the factory radio is missing, thats why the security light could be on and wont turn off?

Re: battery draining down

The radio is through itself and vehicle VATS/security is not affected.
I believe when power is applied, the dial becomes the info center and the radio security code is entered using the radio buttons/knobs.
Owner's manual will show you how to enter.

yup, but I dont have the original radio, I called the woman and told her I need the original radio, so she's calling her son to find out where it is. but back to the problem, as soon as he installed the Pioneer navigation stereo, the security light on the dashboard came on, any reason why?

Re: battery draining down

Please read my original post. The Radio has nothing to do with the VATS. Your problems are all aftermarket install related. This is a Pay Me Now or Pay Me Later situation. If you cannot work on this yourself, your going to have to pay someone to troubleshoot this. Again Read my Post. If you want to find the problem, disconnect all the aftermarket crap and make sure the battery is fully charged. It sounds as though the "Previous Owner" threw a bunch of parts at it instead of fixing the problem. This is not that hard to figure out. If you lived closer, I would be happy to help you.

I did read your post, I disconnected the Pioneer Navigation Stereo, days ago and I do have the battery charging, Iam just trying to get a better understanding on what they could have done or cut, to cause this problem, what could they might have done, so now the security light is on, its still on after i disconnected the Pioneer system

Do you have a Factory Service Manual or anything with the wiring diagram available, and a Volt/Ohm meter, and a Test Light ?. You may be able to find the wiring diagrams on the internet, the Volt/Ohm meter you can get at Harbor Freight for free with a coupon if you buy something else, 20% off coupon buy a test light. I think your going to have to search for whats drawing the battery down. I would start with anything that looks like its been cut and or spliced. You may have to go to a wrecking yard and look for an original harness. Your best bet is to find a wiring diagram and look for anything that is damaged or pinched and check for continuity. All the wires are color coded. I hope this helps.

Re: battery draining down

I don't have anything like that or the knowledge my knowledge is in raising, breeding and incubating eggs for rare Lizard's . lol. But this is what I've found so far. At the end of the day, when I lock the car up, if I use the clicker, which I believe turns on the security system? the car battery will be dead in the morning, if I lock the car using the key, everything is okay, starts right up. I took the car to the Chevorlet dealer, the service manager has no knowledge of this car, he couldnt even find the owners manual on his computer. If I have them work on it, I need to let him know ahead of time, so he can assign my car to a specific mechanic, that worked on these cars, when they where new. he looked at the cut wires and shook his head in disbelief. before they can trouble shoot, they'll need to is replace the entire radio wiring harness, sad, but I when I looked at this car and drove it, I saw the screen in the center and thought it was a smart phone sitting in a bracket in front of the factory radio. When i bought the car, I let my son in law drive it home. when we got home, i was getting ready to call them to let them know, I had there smartphone,LOL. it was my son in law that told me what this was, he drooled over it, I told him, its got to go, I want the factory radio back. I have no use or interest in this stuff, I got my first cell phone 5 yrs ago, a flip phone, which im still using.lol.

Re: battery draining down

Well that's why I offered(if you lived closer)to help you figure this out. Personally I would not take it to the "Dealer". My experience at a Dealer that has a guy that used to work on these cars, is it ended up costing a small fortune and the car still didn't get fixed. I suggest you find a good stereo shop and do a search for the original harness. There are a lot of specialty yards and suppliers, you may have to find a yard local to you to go poking around for the parts. Google is your friend. Here is a link for the wiring diagram https://www.google.com/?gws_rd=ssl#q...wiring+diagram . Here's one for the Harness https://www.google.com/?gws_rd=ssl#q...wiring+harness .I hope this helps.
