Is the relay breaking the connection between the battery and the starter motor?
This relay is to be incorporated into a standby generator system. The instructor has asked us to make a schematic that involves this relay switching from the SCR to the alternator after the engine is started. Could this be a trick question he has asked us?? LOLSince the starter probably draws in excess of 50A through a #4AWG wire, then the relay should not break that path. Since it is a REALLY bad idea to start an engine with the battery disconnected, the relay should not break the path between the alternator and the battery, either. Of the roughly 20 battery chargers I own, all could be left connected to a vehicle battery as the engine is started, so why do you think you need the relay at all?
Is the relay switching supposed to be automatic?
