I have a new-to-me 1985 boat, with a 1985 90HP Johnson V4 outboard. I just put on a new trim sending unit, part number 583358. I put the muffs on and ran it off the hose in the driveway to test it out along with a new rectifier/regulator I just instsalled, and it seems to work, but I had a couple questions after installing the trim sender.
- There is a black wire and a white wire on the new trim sender. The old one just had two black wires. The wires have pin connectors on the ends. There is a connector on the back part of the motor to connect the pins after running the cable back there. It doesn't seem to matter which way I connect the black and white wires (i.e.: which hole I plug the white wire in and black wire in on the connector), it still makes the trim gauge work. Just making sure this is normal and expected?
- The only "problem" I see is that the trim gauge only goes to 3/4 up even when the motor is up enough that the trim sender arm is fully up. Can these be adjusted or calibrated?
- There is also a little bit of resistance (very small) almost on when pressing the trim sender arm down with my finger. It happens for a moment exactly at the point where the gauge reads 1/2 way. I'm guessing this is normal?
Thanks!
