[Vwdiesel] Slowing death of Glowplugs

[Mike & Coreen Smith]

Mark,

I still haven't constructed a "working" model with the LED and blocking
diodes. (Ie: that works right)
The one I built (I think) was the same as your schematic but did not work
like it was
supposed to.  Boss was breathing over my shoulder one day......"What's this
contraption on your bench supposed to be Mike?"....Me: "Err, nothing
Boss......(pushes it aside)"

LOL!
