Flyback diode on output?

Post by peter a »

Hi,
does anyone know if relays controlled by the S40 pro outputs should have a diode or if there are flyback diodes on the S40pro outputs? Specifically I'm thinking about the fuel pump output and if I need a relay with a diode or if I can use any relay (of which I have a bunch).

Any relay would be fine.
