Roll over sensor is basically resistor voltage divider with Hall effect switch. Magnet is mounted on a small plastic pendulum. When magnet is positioned over the switch, switch turns on, effectively shorting out 15K resistor and that results in 0.6V on the middle pin.

If your roll over sensor is busted, while you are waiting on a new one to replace it, you can short out 15K resistor with a piece of wire to emulate correct operation. In my case I removed IC and replaced 15K with O ohm resistor in the pics below.

Some soldering required.... Here are a few pics:
