Under hood fuse box: #26 10 amp accessories fuse

[rockbottom]

No accessories on my tj except the winch
Fuse 26 10 amp accessories shows 1.6 milliamp draw with winch connected or disconnected
Same with Under hood light unplugged

Anyone know what other circuit the accessories fuse could power with ignition off, key removed, and radio fuse removed

What problem are you having? Dead battery?

Might help if you'd tell us what year your TJ is. Fuse #26 in the PDC on my 2000 is a 20 amp and feeds injectors and coil pack. Did you look in the FSM for your year, all the wiring diagrams are in there. All the FSMs are located here https://wranglertjforum.com/threads...ice-manuals-fsm-technical-documentation.4618/

Look like its required but called accessories
Im trying to determine battery draw
I have a post “Parasitic battery draw”
And i think i have found a problem that makes no logic to me
2 Good batteries checked
Fuse in radio battery is dead in 2 to 3 days
Fuse removed battery stays good

Even with key removed if the radio was in the on position when the key was removed the battery draw is there
If i turn the radio iff and revive the key there is no battery draw

Im testing it now with the radio in the off position

With everything off doors closed tge # 26 is still showing a battery draw

I look at this schematic and dont see what would cause this

 

[rockbottom]

Bad spelling
I meant to say
if i turn the radio iff and remove the key there is no draw

Factory or aftermarket radio?

Is your current draw 1.6mA? That's nowhere near enough to kill a battery in 2-3 days.

 

[sab]

Also, you will not see 0mA draw. I would consider 1.6mA within the "normal" or "expected" range...

Sounds like your radio and/or amp is on the clock/memory circuit (12v constant).

 

[sab]

I just did a bit of research. A Group 34 battery should have a capacity of around 50 amp-hours. To determine the current draw required to kill the battery in 3 days, divide capacity by time:

50 amp-hours
————————————- = 0.69 A
72 hours

So, you're looking for a draw of about 700 mA, not 2 mA.

There is a small constant battery drain from the PCM and radio.
