Default Need help tracking down grnding issue on 20A fuse

Well I finally got my 87 TA running once again and its now time to fine out why my battery dies after 3 days. I have been told that it is connected to the 20A fuse. I wil attach the fuse installed and removed in question. Can someone point me to the areas that I should be looking at.





Installed



Removed

Its the fuse nearest the large silver fuse. Also this fuse ties into the under dash lights, when the fuse is pulled, the lights go out, naturally.


Thanks

sounds like you've got yourself a nice parasitic draw. first things first, get your hands on a wiring schematic for everything that goes through that fuse.... what systems does that fuse feed? obviously the dash lights but anything else? it may be possible that one light is staying on constantly.

I a trying to track down a schematic for the fuse box layout and i will go from there. The fuse feeds the lights under the dash but there must be more stuff. If I pull the fuse, these lights go off. These lights are not the issue, once the door is shut, they go off.
