Frans - I agree with your last sentence completely, but here is what
the diagram I've got shows:
I don't usually paste graphics into my e-mails so am not sure if this
will get through to the list unmangled.
If the graphic is not visible in this e-mail, you can see a copy of it at:

You can see that the wire to the starter warning light does have a
fuse, so why not the wire to the alterntor warning light?
I think Mike Gregory was involved in the last modification of the
diagram in the manual. Mike, if you're listening, have you any
comments?
I postulated 2 scenarios for what happens at the L terminal of the
regulator when all is well (open-circuit or +12V) and am still not
sure which is correct. Either will of course serve to supply the
engine timer through the warning light, but if L is held at +12V, I
feel the lead from it should also be fused.
Maybe someone who's taken apart one these regulators might know what
potentials should appear at the L terminal.

Rowland
