Previously I mentioned that turnoff signal on startup may have come from alternator. 
Val Christian kindly informed me that the signal comes from a contact
on Key switch. Those of you with Bentleys can trace on drawing  .  On mine the #50 wire
on relay is connected to contact that closes when starter is used. It is a temporary
ON contact.        Those Germans are tricky , so to understand ALL the possible
combinations is difficult.  Example :  When I look at circuit, looks like we get 
afterglow on the old system during a push to start.       There are many ways to turn 
off plugs design-wise  Key-switch -- Alternator output --Oil pressure --you get the drift. 
Talking about interesting -- to me it is --   was lucky enough to find an old "Relay"
with internal circuit printed on side.Will forward if you need it.Why do I call the
stuff in front of my legs "Crap" ?   --They use Iron blades and pins on push on
connectors ?   .Hell the rusty one I dissected did not even have lube on.
Was a mess of burned -rusted connectors and melted plastic.(1980 deluxe Rabbit)
Shame on you VW.     More to follow as I soon as I can verify by testing.


PS:  My Bentley covers 1977 to 1984. and this morning comparing circuits
years a lot of revisions has taken place so make sure you have the right
year when using drawings.
