Ford F150 XL striped model a/c only - 7700 series CNG 2002 84k 5.4L Thanks in advance for reading and offering suggestions. I just bought this vehicle and can't figure out the problem. My vehicle has a parasitic battery drain. After the vehicle sits for anywhere from 1 to 3 days I need to jumpstart the vehicle. The battery is new. I used my multimeter to test for the drainage and amperage being drained. The drain value is 0.17 amps then after 45min the drain goes to 0 amps. I suppose after the 45 min duration the battery saver kicks in creating the 0 drain result. (Might the battery saver be bad and not working sometimes?) When I unplug fuse #15 which is 5 amps and controls The stop lamp switch, speed control, brake shift interlock, GEN module and RABS module the drain also shows 0 amp draw. I tried ruling out the break pedal switch and have unplugged the switch at the break pedal but the amp draw remained the same 0.17 amps. I don't know what the other items are that are on this circuit. Once again, thanks for your help!
