I have a 79 Johnson 100 hp outboard.
I can trim up by jumping blue trim motor to positive terminal. Can’t trim down?
any ideas?

green for down does not use the solenoid..-----That would make the switch on handle or wiring to be suspect.

I can’t get blue to trim up unless I jump it to the 12v source. What drives the relay?
