Ok, i think i may haveteh 4wd section fixed as much as i can

The prob now is i may have shorted something out.
Now when the hilux is turned off (locked up) the volt-gauge jumps. some dash lights appear faintly. Basically.. at the fuse box, the "gauge" fuse has a variable voltage from .7v-2v <-- this is causing the volt gauge to jump (and flatten the battery o'night)

Any help ? .. im sure my ADD system is still in need of servere repair. But how can i now solve this prob.. thinking of burning the bloody thing.
Any help would be good (feel like its goign to cost thousands to fix)
