Subject:      a Hall Control Unit story
Content-Type: text/plain; charset=us-ascii

hello everyone! I was on the list last summer and
y'all helped me tremendously. I have a few new things
to work on, but before I ask for your help (and have
the time to read all this stuff) I'll contribute a few
things I've learned from the four years I've owned an
'84 Westy.

The first year I had it I would experience this
strange phonomena occasionally when I hit a bump, I
could tell the engine just momentarily stopped, like
perhaps the fuel was cut off briefly. It was strange,
but I was too new to VW ownership to figure it out.
And I probably never would have, until the day I hit a
bump and the motor completely quit. I started checking
everything I could think of, and eventually got around
to checking wire connections. I had forgotten that I
had left the key in the "ON" position, and when I
happened to wiggle the 7-wire connector going into the
Hall Control Unit, the motor turned over! After some
fiddling and the arrival of a helper, I determined
that everything worked fine if I held the connector in
the just exactly perfect place - one of the wires had
broken, inside the 90 degree bend of the connector.
Luckily for me, I had another 84 as a parts bus, so
the fix was simple; cut the seven wires and splice
them into another connector. This has worked fine ever
since. I would think this particular problem would be
extremely rare, but maybe it will help someone diagnos
a motor that won't run for no seeming reason someday.

And for a similar story, see my next post "A fuel pump
relay story"
