Why does my power for accessories and radio come back on and kill my battery. If I lock the doors, it sets of the alarm. Could it be the delay relay going bad or something up stream from it turning it on ??????
Any help would be appreciated.
Thanks

 

well u need to first find out whats draining the battery
so u need to do a parasitic drain test

the bcm controls the power down system, but something is keeping it awake
could be a simple door jam

 

I see the radio and any accessory plugged into the cigarette lighter come back on after 20 minutes or so. the interior lights do not come on, so i don't think its the door pin. when the radio comes back on, i here a relay click just before it comes on.

 

well u need to plug everything out of any cig lighter
and do a parasitic drain test
