The correct term is "self amalgamating tape"

But, hey what ever works....

When I was looking for it last year did not know what was
called....finally found it under self fusing....<grin>

Anyway thanks for the new knowledge....

have fun....sno

Correct Scientific Terminology:
Hypothesis - a guess as to why or how something occurs
Theory - a hypothesis that has been checked by enough experiments
  to be generally assumed to be true.
Law - a hypothesis that has been checked by enough experiments
  in enough different ways that it is assumed to be truer then a theory.
Note: nothing is proven in science, things are assumed to be true.

I used some similar stuff to do a bunch of connections when building my
power system.  It's pretty good you just un roll it, pull the backing off
and wrap it around and it bonds to itself.  Good stuff, but I noticed
that it doesn't take sunlight well.  I did a number of solar panel
connections with that (or something like it) and it does tend to break
down pretty quick.. get brittle in the sun and gets cracks etc if it's in
full sun light for a season or so.  

But on the inside I wrapped that stuff over all the terminals and where I
made a wire connection and it seems like it's doing the job and holding
up well after 2-3 years.

Ohms law showed me i'm getting some resistance between my primary turbine
connection and the first cut off switch on the DC positive side, so I
cleaned that one up and got some improvement, but there are some others
that need attention I reckon since i'm still down on amp production
according to the voltage controller remote meter.  Hardly surprising
after 3 or so years of running without a hitch.

My new (ish .. his first winter here) dog Vinny got into a spawned out
salmon or something and got the salmon poisoning so I've been dealing
with a sick dawg... not had time to go through all the connections in the
hdyro, but i'm digging Ohms law (which now I remember learning about in
highschool I think.. a long time ago).  Very handy indeed.

here is vinny

I'ts one of those rights of passage -- every dog around here eventually
gets salmon poisoning so you just have to stay on top of it. The salmon
wash up through the season and the creek is  only about 100 yards from
the house.. pretty sure he found one and had a little snack.  Just have
to make sure he drinks a lot and give him a good dose of tetracycline for
a while.

Pain in the ass since the vets are closed due to the holiday but I think
I got him on the anti-biotics in time.  Poor little pup .. the salmon
poisoning can kill them if you don't handle it right

cheers you guys and happy new year!

Then just keep the sunlight off it! You can do that with an outer wrap of black
electrical tape.

I am also a believer in 3-M "Scotchkote", which you can find at any electrical
supply store and perhaps the big-box stores.  It is a gooey, sticky liquid that
you brush on a connection.  I let it dry for about one minute and then wrap with
Scotch 44 electrical tape.  The tape and the goo sort of combine into one
weatherproof blob.   Then you may want to add another layer of Scotchkote and
tape again.  I always use Scotchkote with an outer wrap of tape to exclude the

The idea of self-vulcanizing tape isn't new.  Back in the day we used "Tar Tape"
which was nothing but old-style cloth friction tape with 4X the normal amount of
tar added.  In the Florida sun, the tar would melt into a blob around your
connection.  The stuff lasted outdoors for years!

Dogs make great friends, but they sure can be an expensive pain in the ass.

Interesting!  I do much the same thing to detect bad grounds and bad neutral
connections.  I jam a screwdriver in the ground and measure from neutral to the
screwdriver.  If there is any significant voltage, you have "issues".
