Starter clicks using the key, engine starts by jumpering the relay

You say "clicking," is it just one click, or a series?

A series of clicks or "buzz" indicates low/ bad battery, dirty battery terminals, bad cable, connections, in no particular order OR a LOOSE connection at the starter

One click could be bad starter solenoid, or starter, but that does not explain being able to crank it by jumpering.

It’s a series of clicks, same as when a battery is dead.

I connected my meter to the solenoid post on the relay and got 0 volts with the key in the start position. I’m out of time for today, heading to the circus with the little lady.

Thanks for all the help so far, I’ll get back to it when I have some time!
