Cable diameter
The first thing you need to do
is check if the cable diameter
used corresponds to the elec-
trical diagram for your type of
Volkswagen. You should never
assume that the previous own-
ers did everything right accord-
ing to the manufacturer specs. In
many cases "quick" repairs were
carried out and never corrected
after that. It wouldn't be the first
time an electrical cable was re-
placed by a cable that was too
thin (thicker isn't so bad, thinner
can have nasty consequences).
You can find the electrical dia-
gram for your Volkswagen in the
Bentley Publishing book series,
and compare if the diameter of
the cables are correct.

The formula and the method to
determine the diameter of a ca-
ble can be found in edition 21.
We are going to repair the green
cable with black stripe, the diam-
eter is 1.00 mm (picture below).
First cut a piece of the cable,
strip the insulation, then you are
sure that the copper conductor
has its full thickness. According
to the formula below, 1.00 mm
diameter corresponds to a diam-
eter of 0.75 mm .
