RE: [doc] radiator fans circuit

["Richard Hutchinson" <dickyh11@xxxxxxxxxxx>]

The silver box you refer to is a thermal trip which is designed to cut
power to the cooling fans in the event of an overload.

Why have it when other cars don't? Ask LUCAS! I personally have a very
low opinion of the whole electrical system on the car, there are some
unbelievable wiring gaffs that anybody with a GCSE in electronics
wouldn't make - Lucas have got to come pretty high up on the list of
those responsible for the D's failure

If your thermal trip is cutting power to the fans prematurely it may be
faulty, or it may be that there is a genuine fault in the circuit which
it is correctly protecting against - you'll find that out when you get
the new trip installed.

The manual override switch you have discovered has been added in to
allow the driver to flick on the fans if the temperature starts to rise
but the fans have not come on. It's actually quite a handy idea.
