Changing outboards vro 1990 90hp, just realised the one I’m putting on has 3 wire tilt trim old one 2 wire, I’m trying to figure the easiest way to connect it can someone help me out please?
Thanks for the help.i just went back to the solenoid 3 wire setup but tilt trim is struggling on the bigger single ram, I'm starting to get a bit annoyed any advise thank you.
Thanks for everyone’s help and advise got it sorted
3 wire trim motors have power supplied to either one of the colored motor leads, while the common black wire is always grounded. That is, power is supplied to one of the colored (green or blue) wires, and the other colored wire is left UNCONNECTED (not grounded).
2 wire PTT motors always have either power or ground on them when the trim is operating. power on blue makes her spin in the up direction.
Therefore I believe some relays can be used for a 3 wire trim motor. If the relay has 2 ground wires on it, one to complete the circuit to energize the relay and the other to supply ground to the motor, when the relay is not energized, you should be able to disconnect the ground to the motor on both relays and it should work with a 3 wire motor. Remember to ground the black wire..
