power trim issue, 87 45hp classic 50

[Midwestangler]

The pump number is 92975a24, end of last last summer the trim would go up but not down. So I bled the lines and just hand trimmed it for the last couple outings. This spring I chased the power with a multimeter from the button in the throttle back to the pump everything was ringing out accept what I assume is the down solenoid. Bought new solenoids and changed them out now oddly the pump does nothing. When operating the switch the post on the solenoids transfer power but the pump doesn’t respond and the things that’s weirder to me is the solenoids don’t click at all. I would think if the pump work last summer it would at least hum if it was on its way out. I never paid attention to listen to the solenoids before but I’ve not know these types of solenoids to be silent. Any advice would be appreciated. Or if by some miracle someone has a wiring diagram for this setup I would greatly appreciate it. Thanks in advance

Here's an older wiring diagram that might help.

Thanks that’s a big help it’s how I have it wired but it’s good to know for sure.

Is there anyway to test the pump itself? Can I jump power directly from the battery to one of the leads on the pump itself would that make it move if it still works? I don’t want to burn it up if that’s not how to test it. Sorry I’m a little lacking in my electrical knowledge.

Check to see if the motor is getting voltage when you operate up and down.
If it is, take it apart to check the brushes.

Thank you I will do this as soon as I can find time. Really appreciate your help

If it worked before changing solenoid you left the ground wire off.

All ground wires are attached properly.
