Dying Battery Issues

[Splatmaster527]

Ok so a while ago I went out to my truck after it sitting for a while and it was dead. Not normal but not a big deal, jump it and go along with life. Then the next day its dead again so I jump it again and started wondering. The rest of the weekend it kept starting and running fine. A week later after sitting for the week... Dead.
Went to Autozone and got a brand new Optima Yellow Top
Truck worked great again all weekend and I figured the problem was solved and it was just an old battery + winter cold...

Then the next weekend I go back and try to fire it up. Dead again. Now I am a bit pissed. Got a jump from a minivan (funny hearing the engine almost die from the load on the tiny alternator) The next day I walk out to my truck and the radio is playing... random

So thinking the radio had something to do with it I unplugged the headunit from the harness next time I let it sit. Come back and the truck fires right up...

Now I know that the radio is somehow the problem. Anyone ever had this issue? Is it a wiring thing or is my headunit screwed?

I also have a viper alarm I recently got put in which no longer remote starts or locks the doors since the dead battery issues so that's another problem...

I have the same issues . Dies with in a week an half is I don't run my truck . Don't know what it is either . I got an aftermarket dash and clifford alarm. ( had it since 07 ) and the problem just started last year so I don't know that has to do with it

Does the date you got the alarm installed and the date you started having the battery issues coincide. Could possibly be that whoever installed your alarm screwed up the system somehow. Radio should shut off when doors open after removing the key. Sounds like a problem with the door switch which is built into the latch.

No the alarm worked perfectly for about 2 months then I had the issues...

Stupid question but does the radio stay on when you take the key out and open the door or does it come on randomly when you're not around?

Stereo stays on until I open my door , as soon as i soon as I open my door everything shuts down like its suppose to do

 

[Splatmaster527]

Mine will turn off when I open the door like it should it just turns back on sometimes.

Sorry I can't be of more help to you guys. Sounds like a glitch in the bcm but I know nothing about the bcm.

 

[Splatmaster527]

Would the BCM cause the problem to happen only when the radio is hooked up? Would a new BCM be a fix or reprogramming or something?

To tell you the truth, I don't know of a solution to your problem. Hopefully, some else more knowledgeable will chime in.
