Date: 10 June 2018. Proper
Attachment of a Terminal End.
32-volt battery bank troubleshooting and eventual replacement there
were problems with two 4-gauge wires. One went on the #8 battery terminal.
That positive wire end piece had broken. I replaced it. There is a
right way to put on a new terminal end. Here's how to do it
This is the
PROBLEM ↓ connection. It was loose when
I removed the cable from the battery stud.
Tools, ready for the task at hand:
working anywhere, it is important to observe. As I was taking the
wires off the batteries I saw one cable end that was loose. The loop
had broken. This is unacceptable. It needed replacement.
I kept notes on where the cables belonged. First I
made a schematic of what was there.
Then, as cables were removed I wire tied them. All were numbered so
I could replace them properly.
Note that both the nut and lock washer were wire tied
to each end. That way they wouldn't get lost.
The direction you
squeeze matters. Clamp so that the squished part is on the same
plane as the business end of your fitting. In other words, make it
flat. That is the best way to get a good tight connection that won't
First I slid a 2" piece of heat shrink onto the
4-gauge wire. The new terminal end slid on easily too.
Then I began the process of tightening the
terminal end to the 4-gauge wire.
Please note that were I professional I would have a pair of real
crimpers for this task. As a budget boater I have learned to use
vise grips for crimping everything up to 4 gauge. Larger gauge,
sizes 2, 1, 0 (zero) and 00 (pronounced double aught) will not work
with vise grips, however size 4 and smaller wires do just fine for
First I squeeze to get the flatness started. Opening the tool, I
continue to tighten the screw on the vise grip's handle 1/4 turn with each
compression. This is NOT the way a pro would do it. He'd have a real
I find this method
works well for me.
This is part of the group that belongs on battery post #8.
Note that the PLUS SIGN
by the positive terminal was painted over with red nail polish. It
is now easier to see.
After the terminal end was
attached, I used the lighter on the heat shrink.
Then it was a simple matter to install this cable onto Battery
More tomorrow. A subscriber is installing a new
battery bank and I wanted to be sure he knew the direction to crimp
on the ends. It really is important to do this part correctly.
Some ends such as those for smaller gauge wires have
a split in the middle. When you squeeze the wrong way the wires can
escape. That is never a good thing.
Now don't forget
that if you need to buy parts please be sure to use my
link. There is one found at the top of every page. It really does help
me and costs you nothing. I've got a
List on Amazon too... trying to save up for a new Paperwhite or
maybe one of those 10" in 64G Fire's. My Paperwhite is not always
taking a charge.
End blatant plug.

I have been having a lot of fun
out here. The goal is to post shorter pieces more frequently. Still
when given a choice between writing which I do enjoy and reading,
especially when a favorite author has a bunch of books on sale...
Well, suffice it to say if you have stock in Harlequin's
Betty Neels books found on Amazon, you're getting rich!

Thanks for reading.
Are you a fan of vise grips? I use them for practically
Do you have a legitimate pair of crimpers for wire work?
