alternator, split charge etc.

I've fitted a new alternator (was almost a year ago now) It has the usual terminals on the back and one for a rev counter.

I'm thinking of using a relay to split-charge to a second battery (for lighting and other gubbins).

Question is, is there a connection I can use that is only live when the engine is running? so I can use this to trigger the charge relay.

I don't mean an ignition live as this is live before the engine is started.

Second question, Most relays I see around are 30 or 40amp. will this be suitable for a split charge relay with a 65amp alternator? Logic tells me to use a 65amp or more relay.

for a split charge relay, they trigger on rising voltage and put a charge to a stand by battery when the system volts rise above 13, ie when the main battery is charging. ( SMARTCOM RELAY £10.95

I have a system installed which uses a small relay to operate a high amp relay called a "Coil Hersey" relay which is very reliable. the coil is made in USA.
