What is the difference between a battery relay and a starter relay? I have a Rans
S12S and the circuit diagram for the Rotax 912ULS engine shows both. But I
just got the plane and it only has what I think is a starter relay with the rotary
starter switch and a simple SPST master switch. Do I need to add the battery
relay?

Among other things, a battery contactor is designed for continuous duty and typically
draws about 3/4 of an amp when energized.
A starter contactor is designed for intermittent duty and draws about 5 amps when
energized.
