Our 99 F150 went into security a couple times but would start after I charged the battery. The truck hasn't been used for about 6 months and now I seem to have lost some of the power circuit. I have no power at Nos 20-24 fuses in my fuse panel and I have a wire to my ign. switch that is dead also. Where do these fuses get their power from, I seem to have power from all circuits in the underhood panel. Thanks in advance for any help.
