2005 mustang gt
shaker 1000
​​​​​​​My battery has been dying recently. new battery and new alternator. did a parasitic draw test getting 132mA draw. i pulled every single fuse never got below that. is there anything else i can try or do?

 

Try disconnecting the power to the Shaker head unit.

 

I pulled the fuse for the head unit. No change in mA draw

 

Perhaps the sub-woofer in the trunk?

 

I suspect that in many cases the capacitor(s) in the bags power supply are not fed by any fuse: this is for safety consideration when vehicle is parked and not in use: hit by another, bags are expected to deploy, especially in older models, no matter what.

A leaky capacitor could account for the current flow. Just a thought. I may be full of crap.

 

I’ll take a look into that I’ll try anything at this point my battery won’t last 3 days without being driven. Thanks

 

Radio/CD player & mainly the alarm (ie. just having the doors locked) are very common causes of major battery drain with these years
(ie. my car)
