[T3] no start issues...

[Dave Hall]

Easier fitment is to use the connector in the return from the
ignition/starter switch to separate the circuit and fit a start relay near
the battery.  That works like a charm as well, and is less trouble!

I suspect the (rear-engined) Porsche batteries may be in the front to
improve the weight distribution as much as shortening cables.  Indeed,the
cable to the starter motor is much bigger section and it must be quite an
extra cable weight and cost to site the battery there.

Hi there
Other than the obvious tests for generator, regulator and battery function,
(which should have been a first step), the problems with older VW starters
are the lengths and the current age of these looms.  A solution is to use a
12v Ford, (this is the application, generic is fine), starter solenoid,
mounted on the trans case bolts or into the lower section of the double-wall
engine compartment near the starter.  I have no means at this site to show
the wiring and gauges of wire needed for this install, but it cuts the
length of the start current to about two feet from the 12v source, your
battery.
This, of course, is the problem with the now well-aged wiring and, indeed,
with the original system.   In short, (no pun intended), this means that the
ignition switch, instead of being a "power routing source", (from rear-mount
battery forward to the switch and then back again to the starter), is, with
the additional solenoid, merely a switch again, (also saving these
increasingly rare items, from early deaths by electrocution).  The 12v power
is routed directly from the battery to the starter, with the ignition switch
telling it when to do so.
I have used this for years with 6v and 12v models and it works like a charm.
These "Ford" solenoids need to be sealed, (plastic-dip brush-on electric
wire coating), and then you might just have a reliable vehicle that doesn't
require a hill on which to park.
Of course, the charging system must also work, as stated earlier.
This, incidentally, is the reason that Porsche batteries are in the front,
under the spare, nearer the ignition switch...
I hope this helps.
Best regards,
FE Meek
