Beginners 12v Automotive Electrical Repair

Beginners 12v Automotive Electrical Repair


G’day Brett here. I’m about to show you how
to complete simple beginners level 12 volt
electrical repairs on your vehicle while travelling.
As well as what tools you’ll need to complete
the job. Now before you start any repairs
make sure your ignition is off and the keys
are removed. If there is a major fault you
may need to remove the negative cable off
your battery but if you have a computer controlled
vehicle be sure to check your user manual
to make sure it is safe to do so. Now during
my morning pre start checks I discovered a
wire on my washer bottle was close to breaking
off. So I gave it a little wiggle and it broke.
Now as I’m not carrying the specific connectors
to fit inside the electrical housing I’m going
to replace them with spade connectors. And
this is how.
Using some wire strippers cut off the end
of the broken wire to remove any damaged or
corroded sections then strip 5mm or so of
insulation off the end of the wire.
Thread this in to your connector and crimp.
Ideally if you’re carrying a 12 volt soldiering
iron you should solder the connection as well
for maximum reliability but that requires
you purchase connectors without the insulation
attached.
And that’s your repair job done.
So now what you need to carry is a set of
wire strippers. Now there is different types
this kind as you saw has a little difficulty
in stripping really fine wire. But I still
quite like them. And you’ve got your crimping
tool. It has different colours to match the
different size connectors you’re using. And
then also a different selection of connectors.
So there is the spade type such as this or
you might have bullets or ring types. Have
a good selection just to accommodate any different
variations on your vehicle. There’s 3 colours
which typically come out. The yellow is the
biggest wire size diameter that can fit in
the hole, followed by blue and then red is
the smallest finest wire. So I used red on
these because it was quite a fine wire and
if you crimp it and you have too big a hole
the wire can still pull out. So try and set
one to the correct size. And that’s your repair
job done. Now I’ll keep this because I can
buy special connectors which are designed
to fit in here. Later on I’ll probably cut
those off and reuse the original Land Rover
fitting just to keep everything neat. But
that’s for another time.
