Re: Fuse for Tilt / Trim
No, just hold it to the top post where the red battery cable connects to the solenoid.
I just want to see if it works or not. If it runs, the problem may not be in the box at all but in the switch at the control.
The solenoid is just passing the battery voltage from the top large post to the bottom large post. The two small wires at the sides of the solenoid turn it on and off. If the solenoid is new, then it should be somewhere else.
If that were my rig. I would rewire with two solenoids as close to the motor as possible, and use the control switches just for activating the solenoids.
