This is not directly Vanagon related, but inasmuch as electrical problem
require a certain amount of work over the years, and given the numerous
camping equipment upgrades done to our Westies, here goes:

Over time I have seen reference to using the ratcheting style connector
clamps, but never gave it much thought. Recently, I had to help friends who
got in trouble on an installation contract deadline when an employee
suddenly quit on them, so I helped out part time and probably did about a
hundred connectors of all kinds. I was using some old-style cheap crimpers
and strippers I've had for 30+ years. When I got to use the company's new
stuff, I tossed my old ones in the trash. They didn't even make it to the
"reserve" or "give to someone who needs it" piles.

I replaced it with two pair of Klein Tools stripping pliers that together
strip a wide range of wire sizes. I also ordered a ratcheting crimper from
eBay. The pliers are very high quality, though, and do a superb job. <

Just a thought if you do your own electrical work. Throw that crap away and
get something good. There is a world of difference in the results and the
time you will spend.
