I have a 1976 Johnson 85hp motor that I am installing a new aftermarket tilt trim switch on. It has 3 wires as does the trim motor. My question is can I just use power to the switch, and ground from the motor with the switch being power up and down. No relay, or solenoid just wired directly from the battery. Or will this cause some kind of problem? The reason I ask is the trim has a new pump on it as well but I don't have any of the other parts. (solenoid, relay etc.) But it should work without it. I have tested this with my battery jump pack and it seems to work fine. Is there dander of overloading something?
