IOD fuse keeps blowing

So while trying to get my brother's '92 YJ started, I noticed that the IOD fuse (15amp) keeps blowing.
What circuit does this regulate?
Any idea why it pops the second we try to start it?
Will this fuse keep the Jeep from starting?

IOD stands for Ignition Off Draw. I am not 100% what it works with in the YJ.

You must have a short in that circuit. The IOD circuit usually powers items like radio memory IIRC. Pull the IOD fuse and test each side of the fuse socket with the key in the ON position. One side should not have voltage. If it does then you have some sort of voltage feeding back to the fuse as well as voltage feeding to the fuse. What (re)wiring did you do recently?

Well, the PO installed the ARB locker on that circuit.
For some reason it seems like it's pulling way more than it should.
I've disconnected the ARB for now.
Anybody know what amp the ARB lockers solenoid is supposed to draw, and what fuse size I should use?
I'm probably going to just run a circuit right off the battery.

IDK what the AMP draw is. Maybe the solenoid is NG. In any event you may not have a short, but too much load on the circuit. Doesn't ARB have a website that would show you how to set the locker up?

IOD fuse

I have a 92 yj 2.5 and I have a problem. One day it wouldn't start. The alarm light on the dash started to flash and it just wouldn't crank. So I check the fuses, they were all good. But when I removed the iod fuse I was able to start it. If I put it back on it will the same thing. Any suggestions?

You have an alarm that is not stock. It hooks up and probably has a kill feature. The IOD probably powers the alarm and when you pull it you are disabling the alarm.
