I need to ground the input to the regulator when not in use i.e. ground the yellow wire.

I think a relay that is grounded on the NC side and then fed the field voltage/idiot light voltage when activated should do the trick. So when not in use the alternator field windings are not fed any voltage and cannot 'pick up' any voltage!!
Did you manage to get it working? This sounds like a great mod to use wasted energy to keep the battery charge.

Cheers,
