Battery drain

1994 f250 .33AMP drain on the #8 fuse circuit. I have unpluged Radio,glove box lite,spom from the gage cluster. Does any one know where to find the plugs that come from the # 8 circuit,without having to open up the loom? The map lites,cargo lite,courtesylites and the door lite all work fine with the fuse in,but I do have a drain. With the fuse out I only show a few milly amps. Thanks jr37

Is the underhood light on that circuit? Have you checked it for proper operation?

How did you measure the 0.33A drain (what type of meter, how was it set, and where did you place the probes)?

No hood lite,disconnected the neg. bat. cable hooked the test leads one to cable one to bat neg on a 0-10 amp scale on a crafsmen multi meter. The wiring diagram shows lt grn-yel coming from #8 fuse going to a junction point to Engine comp.LT (none)-psom I have pulled connector no change-radio Pulled connector No change-glove box LT no change-right door sw it works ok. Another connection to map LT inside cargo lt(is this the light outside the cab?-power mirror sw ( no power mirrors)-left door switch works light ok- one wire going to the light switch for turning the courtesy lights on. All interior lights seem to work fine. I would like to find the connector that go to the out going circuits from the junction points . Also with the key in the run position and the #8 fuse out you have all the lights and chims. Both fuse contacks in the fuse block is hot with the key on and fuse out. Is this normal? Or is there somthing feeding the circuit when it is not suppose too. Thanks Jim(jr37)
