Is there a place on a bike that only has power AFTER the engine starts?
I want to change my lights to operate only after the engine starts. I'm
tired of having all the lights on when trying to start it. I think it's
too much drain on the battery. Maybe I can tie the light circuit to the
generator output or on the regulator somewhere.
How about buying an automotive relay with a heavy resistor that is normally closed (8EUR or so in France), and connecting the control pins to the circuit going to the starter motor and the load pins to the lighting circuit . When current flows to the starter motor, this should open the relay, cutting the circuit to the lights. You'd have to make sure you buy a relay capable of taking the relatively high current in the starter motor circuit.

There may well be a good reason why this won't work but I can't think of any at this moment in time. I stand open to correction.

Come to think of it, there is no need to connect to the starting circuit directly, since this itself is controlled via a relay. Tap into the circuit that controls the starter relay.
