crimping battery lug
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...

Take the lug off, clean it, and solder it back on using flux.
Sounds easy.. But do you have any idea how big a soldering iron you need to handle Battery cable (4ga or bigger) wire.
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.
You can buy small butane torches. Not a butane soldering gun but an actual torch that uses butane. I use that for soldering and heat shrink. It’s small enough to fit in confined areas. Puts out enough heat to heat up a copper lug but not enough to melt anything around it!
