Sundance 850 Marin No Power To Circulating Pump 2.

I got a hot tub given to me by my father in law. It’s a Sundance Marin 850 (not sure the year)

Sn3 and flow errors were present. Changed the flow sensor and the heating sensor, that eliminated those codes and everything seems to be working except the circulating pump #2. So the message seat and a few other jets that I’m assuming run of that pump don’t work. I checked to if the mother board is giving Power to pump #2 and there is no power going to the pump from the mother board. My question is: is the mother board bad? I can’t rule out the pump being bad if it’s not getting power. Is there a fuse somewhere? Added a picture so you can see the mother board. Picture is of someone else’s but it is the identical to mine.
