I just bought an 81 toyota pickup and the battery has been dying on me. The reason it is dying is because the terminals are loose however I cannot figure out what to do because I cannot find terminals with fuseable links. Any ideas on what I can do? I've tried to tighten the terminals in any way I can but I can't get them tight enough.

 

I use marine terminals on all my vehicles.

A ring terminal can be soldered on the end of your fusible link
