I have a parasitic drain of .15 amps on my battery. I have a 91 XJ with a 4.0l engine and aftermarket stereo. I know there always is a litle bit of a drain but I can't find any specifications for whats acceptable. Anyone know the specs. thanks in advance

 

i think its somewhere around 3 miliamps

 

Ignition-Off Draw (IOD) refers to power being drained from the battery with the ignition switch in the Off position. A normal vehicle electrical system will draw from 5 to 20 milliamperes (0.005 - 0.020 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. The 20 milliamperes are needed to supply Powertrain Control Module (PCM) memory, digital clock memory, and electronically tuned radio memory.

Hope this helps

Edit: I believe Captainwoot is correct on this one, I was trying to remember but could'nt remember the exact figures.

 

You may have an amp that is always powered on, you should have yellow wire constant power, red- accessory (on w/key) and blue/wht signal from stereo to turn on amp.

 

captainwoot is right i had my decimals in the wrong place , sorry about that
