Hi Rene - a DPO is a 'Dumb Previous Owner', I believe.
I agree they do tend to run on, but due to deisel-ing, not because you still
have power
to the coil. If running-on is stopped by removing a wire from the coil then
there is a
definite electrical fault which should be investigated and fixed. That is why
the
anti-run on device lets air into the manifold instead of doing something with
the coil.
Incidentally, I have never had a car with an anti-run on valve and had always
assumed
that they were always energised and closed when the ignition was on and always
de-energised and open when it was off. But when someone mentioned it clicked a
few
seconds after the engine stopped I realised that it must be normally
de-energised and
closed when the engine is running or stationary, energised and open as the
engine is
turned off, then de-energised and closed again when the engine has stoped
rotating and
the oil-pressure drops.
Cheers,
PaulH.
