'91 Camry wont stay running,
 

So my camry was displaying all sorts of warning signs when i accidentaly broke the middle fuse thats on the positive battery lead. Symptoms were as follows: The rear running lights wouldnt work, interior lights only worked when i pressed on the brakes and the charge, check engine light and ebrake light kept coming on.
This morning i went to start it and i needed a jump just to get home, after jumping it, it lacked allot of power, barely made it home and now it wont start unless it is jumped. My question is, what is this peice called here so that i can replace it and see if it solves my problem
