Malcolm,
Yes, it's activated by the ignition switch and it's a continuous
burden, if you can call 0.73A a burden on the car electrical system.

Not relevant if it's activated by the ignition switch etc, yes if it's there
24/7. Rough calc, if your total battery capacity was 140AH that 0.73A would
drain the battery in 200 hours, think that right?

Remote switch sounds quite attractive then.
Roman,
If it disconnects when ignition is turned off, there must be a circuit
which does not go through the disconnect switch then, so that there is
power to turn the switch on again. Right?
That it switches off if battery voltage goes under 9 V, could that give a
problem when cranking in very cold weather when the voltage would go very
low?

Ugo,
Yes, each contacts is paralleled by a 10A switchable circuit breaker
fitted on the dashboard, next to the isolation control switch. This
ensures continuous power supply when the ignition is off and in the
unlikely event it doesn't blow it can be disconnected manually.
If the batteries are in good condition that should never happen. 9V at
the battery output indicates it's already a piece of junk.
Accidentally, one battery in my LC was found faulty recently . It did
not hold the charge and would drop to 9.5V under full load (about
200A), but that did not affect the isolator. Engine starting was
sometimes sluggish but the isolator never opened the contacts.

That makes sense, contactors should pull in at around 75% of then normal
coil voltage and often won't drop out until 40% to 50% so a 12V contactor
should be good even if the voltage during cranking drops to 6V.
