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.
