Sorry to insult your intelligence:)

I assume the Bentley you are using is for the MK3.
I don't have that one.

You got me curious now though.
Maybe it limits current going through the coil.

It's been a long time since I popped a relay cover off, I may have to
dissect a spare in the garage now.

question.... ;^)

mmm.... nope

:^)

What I saw is certainly a resistor. Got the colour bands on it.

It would be hard to take a pic of. Maybe I could get a shot of the
diagram on the housing.

I wish I could recall what little I learned of electricity when I was
younger, but I know for sure there's a difference between a resistor
in series within a circuit, and one in parallel. Why it's there I
don't know.

Neil.
