Do some checks with your meter. Double check but ‘B’ should be battery and 'M' starter motor. Personally I’d check electrical operation rather than short it out. Clean up the terminals and connect it back to the battery but leave the starter motor lead off. Ignition on, in neutral and thumb the starter. You are looking for battery voltage at the starter motor lead.
Then you can check control side of the relay if first test doesn’t work. As in, do you get 12v on the solenoid control when pressing the starter. Essentially all that relay does is move a contact over so the battery voltage reaches the starter motor through the thick leads.
Normally you can hear the solenoid click in operation.
