I've been chasing the reason my voltmeter drops when switching load on. The gauge shows just over 13v with no load and drops to just over 12v with everything turned on!
New battery (even though the old one tested ok) and change of alternator and still the same.
I then checked the alternator output voltage and that is 14.1/14.2v no matter what load, then checked at the battery (in the boot) and that is the same!
so looks like there will be some dirty connections - will have to see if I can borrow a thermal camera

Small correction if I may.Your relay coil should be connected with pin 85 to ground.

I can't be any fairer than this can I

I'm only a little worried as last year in the heat of Le Mans the fuse/relay box started to melt. Since then I've fitted a modern Focus one so thought I'd fixed the problem but obviously not. Some time in the near future I'll take the dash out and remove the redundant wires and reterminate the rest. As well as sorting out the heater system.

True the relay will work either way round unless there is a diode inside but the presence of a diode is often not marked on the relay so it is best to use the correct (DIN72552) pin connections at all times.

Good point. There is nothing worse than purchasing a standard relay and later finding out it has a diode or resistor in it when not wantedSteve
The proof reading department will spot my error and alter the final product as required
I was undioded whether to reply or not but in the end couldn't resistor it
