Hopefully this helps:

I think I'd be taking some jump leads a sticking 12v across the wires that go directly to the motor pump (big terminals on the solenoids). I can never remember the colours but think the red is live, blue is "up" and green is "down". Assuming that works & that the trim pump is ok, id then verify the solenoids/relays are working and that there isnt an inline fuse youve popped somewhere. If the main power side is fused, it'd probably be quite a biggy, like 40A ++

Aslo try giving the motor a few taps with the handle of a screwdriver or something, brushes may be stuck.

Just trim it all the way up and down a couple of times and it should sort itself out
