Well, it seems my salesman neglected to tell me there's a solenoid on
the powerpack itself for switching power to the pump. The unit's just
arrived and I see no point in switching the main feed to the pump when
that's what the solenoid's for. The solenoid's coil is showing up at
6.2ohms, so it's only a couple of amps at 12v. Quite easy with bog
standard relays or FETs...

Thanks very much chaps,

Tim
