2009 Outback starter motor problems: Maybe a bad relay?

[Ravenwoods]

At first the starter would engage and turn the engine over a couple times and then quit. After trying a few times it was only silent, not even a click. I replaced the starter motor but the solenoid does not appear to be receiving power from the signal wire.

I looked at the owner's manual list of fuses and for the fuse and relays in the engine compartment and it says something like "except starter motor.". The passenger compartment fuse list in the owner's manual says fuse 21 is the starter relay but the fuse is still good. Somewhere I think I read that the blue boxes to the right of the small fuses are relays and one of them might be for the starter. Can someone tell me where to look?

My battery is good and the voltage at the positive connection on the starter motor is the same voltage as the battery.
