Hoping I am missing something obvious as I am not an electrical expert. I am simply swapping out the stock valves and empty pumps in my system(they are all either broken or leaky). I was thinking would be fairly plug n play, but maybe not?

I replaced all the empty pumps with these https://www.wakemakers.com/attwood-t...-pump-800.html
and i replaced the sprinkler valves with these: https://ussolid.com/motorized-ball-v...-polarity.html
I have the Deutsche connectors all wired up and I am trying to simply test them before mounting everything and I keep blowing the fuses. The empty pump works, then when i flip it to fill the fuse blows. Any help would be appreciated!!
