OK, I am becoming very paranoid.

I have two 88 Vanagons - both of whom have had runaway starters in
recent weeks.

The first disengaged the flywheel but ran until I could get the
passenger seat moved forward, access the battery box, apply a wrench-
and remove the cable from the battery post - which all seems an
interminable period of time. It killed the starter. Had to get a new one,

The second was on the Volksiebus - the 88 Transporter a few days ago.
Fortunately as I was struggling to get the passenger seat moved forward
for access to the battery box - it shut itself off. And, to add to my
consternation - it works just fine an hasn't faulted since! But oh do I
ever know - if it's one it once - it will do it again.!!

I have start relays on both these puppies - never had a lick of trouble
ever - then this = two of the same episodes on different vehicles with
in a few weeks of each other. Totally weird! I have looked at the relays
very carefully - I don;t thinks it;s a snowballs chance in July that
they are somehow at fault.

But what would bypass the ignition switch and keep power to the starter
and keep it running - with the ignition off!!

Any ideas?

And - I's so paranoid over this I think I need a kill switch. Any ideas
on those and were to put them?

Thanks,

John
