Alky troubleshooting, no red light


Good evening, hoping for some general troubleshooting ideas before contacting Julio. I just got my car back together after a transmission rebuild and some other work.
Went to test the alky and it’s not powered on, no lights at the controller or anything. I verified that the alky box fuse is good, also used a test light and there’s power all the way to the pump. The pump is grounded ok from what I can tell. Can you think of anything I may be overlooking?
The kit is from 2018 so it’s time for a refresh anyway, just would rather have it working now if possible. Thanks for any advice!
