Ok, this is on my boat but very well could be an RV question so I hope it is appropriate. While replacing a pump I noticed one of the positive battery cables going into the battery selector switch appears loose in the lug. Problem is there is very little room to work and removing the entire cable is a lot of work.Trying to figure out what hand tool I could use to press the lug back on the cable tightly. I looked online and see people using a hammer and screwdriver and some sort of press. I don't have a crimping press and not sure it would fir in the small area I am working. I have a hammer and screwdriver but not very helpful where I'm working either.Any ideas?

What material is the lug made of?What style of terminals on the battery?It could be possible to replace with bronze set screw type terminal.Bronze set screw connectors

You can buy another cable with double lugs for about $10 on Amazon. How hard can it be to take the nut off the battery and the nut off the back of the perko switch?

Take the lug off, clean it, and solder it back on using flux.

A welding torch would be my first choice.. Though I might do it with a good propane torch. The crimping tool someone up-thread suggested.. From the photos it looks like it does a very professional job. Some of those hand tools I use (on smaller wires) the crimp looks to my practiced eye to be better than some factory crimps. That is one of 'em.
