[Vwdiesel] Trying to get the old diesel to start

Oh yeah, about the solenoids - when I first started playing with them
I didn't think it was right that the plunger would fall out, but if
you put power to them then the plunger is pulled up, into the body of
the solenoid. (And fairly strongly, at that.) In fact there's that
spring behind the plunger to push it down. If you take out that spring
I believe the engine will run even without any power to the solenoid,
but I haven't tried it myself.
