Any ideas appreciated.


Several of the gel-filled wire nuts are listed for underground
application iirc.

I've used them successfully for a repair to the well -- been almost five
years now w/ no problem.

Did, of course, use friction/self-fusing tape liberally and a good wrap
of high-quality electrical tape over the splices for added measure, of
course.

I'd simply go for it and make measured sketch of where the repair is if
rest of wire seems in decent shape. Of course, it's quite possible what
you'll find when you repower it is another failure, then another, and
then another if the overall wire is in bad shape...
