Have a 98 grand Cherokee 5.2l engine it's been draining by battery and when it start sometimes don't want to stay on. I unplug the pos of the battery and put a test light and it came on. I been checking all this time and I finally start unplugging things and when I unplugged the cruise control solenoid the light went off also I hade the bcm unplugged. After the light went off I plugged the bcm and the light came back on. I closed all my door and waited 15 and the light was still on. I start taking fuses out again and now when I take #7 (cluster) the light goes off. I took all my dash panel out locking to se if something was wrong but everything was looking good. Can anyone help me with this problem

 

Ok this is driving me crazy. I check again with the test light and is on again but this time is brighter. I check al fuses again and this time is the big fuse 40A IOD don't know what that fuse is for
