1. Spin up the motor to about 1500rpm
2. Toggle the switch. This connects the motor to the right side circuit. This is a simple current source which sinks about 10mA of current driving the lamp (1.5V, 10mW)
It is interesting, if the switch is toggled when the motor spins about 1000rpm, EC displays "Cannot find solution", but if the rpm is a bit more, there is no problem.
