This fuse is for the body control module, so your draw is probably something controled by the bcm. Get a manusl, get a list, and eliminate them one by one until your draw is gone! Good luck, let me know if you need any more help!

Parasitic battery drain - likely source


Check the number 07 fuse under the rear passenger seat. It serves the Truck Body Controller 2 (TBC 2). The controller fails & is a known source of intermittent battery drain. The will not be blown, it is just serving a bad controller that is not turning things off as it should.

98 Jimmy has a power draw it kills the battery within 12 hrs if you pull the 50 amp fuse for the int batt draw goes away any ideas


Yes Steve I do , that fuse supply's power to the I/P fuse block inside the vehicle . It powers AUX/PWR fuse #13 -20amp , RDO/BATT fuse #19 - 15amp ,MIR/LKS fuse #7 - 5amp , CTSY/LP fuse #8 - 15 amp , CIGAR/LTR fuse #2 15 amp , PWR/LKS fuse #14 15 amp , HDLP/SW fuse #1 - 10amp .Do you know where the I/P fuse block is ? You would need to do a parasitic draw test ! This involves hooking up a amp meter in series with the negative battery post an negative battery cable . Pulling each one of these fuses till the battery draw stops ! How To Perform Parasitic Draw Test EricTheCarGuy check out Eric the car guy's video on the subject !

BFC BATT FUSE 10 AMP


Maybe shouldn't answer and wait for someone to tell us both what BFC means, but it would not be for the BCM. Sounds like what some cars call the IOD fuse-ignition off draw-the small battery draw that is used for the computer memory, radio pre-sets, and the clock, theft alert system. Believe it would be about that same draw as yours, not enough to drain a battery. Still have your owner's manual? It should have a listing of the fuses.

Dead battery after 24 hrs wont hold the charge! baterry is new


Find the battery drain. Disconnect negative cable from battery. Place test light between pattery negative post and disconnected negative cable. If light is bright while no accessories are on, there is a drain. While keeping the test light in this configuration, pull each fuse out and replace on at a time while watching test light. If the light dims or goes out when a particular fuse is out, that identifies which circuit has the drain. Use that information to track down what is on or draining.

Dead battery .9a with pos. term. disconnected unplug radio fuse drops to .4a also unplug batt main fuse drops to .02a


FIRST CHECK TO SEE IF YOUR BATTERY CAN ATTAIN & SUSTAIN A FULL CHARGE FOR 24 HRS, IF NOT REPLACE BATTERY. IF OK, DISCONNECT POS TERMINAL, HOOK UP VOLT METER SEE IF YOU HAVE MORE THAN 8 VOLT DRAW IN THE SYSTEM, IF SO START PULLING FUSES TO LOCATE EXSESSIVE DRAW ON BATTERY.
