Battery still being drained.

[Sooner1970_K10]

I know this is becoming old very fast. So far I know the altenator is good, the regulator is good and the battery is good. I know the horn is good as well. I have removed all fuses one at a time and the draw on the battery did not go away.

When I removed the 4 connector bar from my external regulator the draw on the battery went out. I assumed the regulator was bad. I hooked the regulator back up, the light came back on and then I went over and disconnected the main wiring harness from the firewall where it plugs into the back of the fuse box? The light went out again, so this leads me to believe the draw comes from inside the truck?

I know the draw is from inside the truck and must not go through the fuse box, since I removed all the fuses, one at a time and the light never went out. I believe the faulty component is somehow tied to the brown wire that runs to the regulator, since the other 3 wires on it run to the altenator and I have already checked them.

Can anyone tell me how or where the brown wire runs? A second part of the problem, is my uncle tells me from the looks of it, my ammeter wasnt working correctly in the first place. Could something be wrong with the ammeter itself and be causing the draw?

Anymore advice would be much appreciated.
