Studying Rotax 914 schematic, the main fuel pump is wired to the B+ of the

regulator.



It appears if you open the alternator output switch, they expect the

alternator could run the fuel pump with no battery in circuit???



They do have a 22000mF capacitor from B+ to ground.

OK another question comes to mind. On Bobs Z-8 which uses a SD-8, if the

output relay was opened (not connected to battery or Buss) and you

connected a 3 amp fuel pump motor to the red output of the regulator would

it run and be happy for an emergency? 



Called for on Z-8 is a 20000 to 50000mF capacitor connected to red output.



Thx.
