Hey guys, been lurkin here for a while and have found most of my answers by using the search but this one has me stumped, hope you guys can point me in the right direction. I have a 1993 4 door jeep cherokee,4.0, auto. I have just finished changing the motor, the original motor had 277,000 miles on it and the head gasket went and cracked the head. The motor i put in was from a 1995 cherokee with 101,000 miles.......anyways my question. I have a low voltage batt. draw, I have found that if i pull a fuse under the hood marked "IOD" it stops the draw, it is a 20 amp mini-fuse. I do not know what circut this fuse is for and what i am shuting off and /or if it will harm anything. I do not know if the jeep had this problem before i changed the motor because i bought the jeep with the blown motor. A batt. fully charged will be drawen dead overnight with this fuse installed. Thanks for any help , steve

perhaps this will help.
Ignition off draw fuse (IOD) / Vehicle storage
The term ignition-off draw identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. The IOD connector feeds the memory and sleep mode functions for some of the electronic modules in the vehicle as well as various other accessories that require battery current when the ignition switch is in the Off position, including the clock.
