poping fuse in 95 pup. help

i keep poping my "engine, back L" fuse and i cant drive without it. i cant trace the problem. anyone else aver run into this problem?

did you add anything or redo wiring recently?

just got the truck like 2 weeks ago, supposidly this problem never happend befor and it poped out of nowhere. could a bad sensor be causind this? i didnt add anything.

nevermind. all that work and all that stressing and all it was was a damn faulty alternator plug, its the one with the 3 wires not the fatty one. now i feel stupid.
