7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

  • Micro switch installation on Yamaha 704 binnacle control?

    I just purchased a NEW 704 premium binnacle control that came with instructions but does not indicate how to attach the micro switch that is attached to it's wiring harness.

    The switch is roughly 1" x 1/2" and is soldered to 2 brown wires on the
    attached harness.

    Inside the control there are 2 'bumps' cast in the metal plate and there appear to be 2 'bumps' molded into the plastic 'arms' directly above the 'bumps' on the metal plate. I'm pretty sure these 'bumps' will line up with the thru holes in the corners of the switch and the plastic arms will hold the switch in place with a spring like action.

    The problem is, even if the switch mounts in that postion, there is absolutely nothing that will contact the switch 'button' to activate it no matter what postion I put the throttle arm in.

    I belive this switch is the NEUTRAL 'lockout' protection?

    Does anyone have instructions, a picture, something they can scan and email or anything to help me figure out what this switch is for and how to properly mount it?

    Is it possible that a part may be missing that would contact and activate the switch button?

    Any help would be greatly appreciated.

    Have a 704 also, only electrics going to it are for the tilt/trim thumb -beep trim switch. Most motors I have fooled with have the neuteral start switch on the motor itself. Will dig out my paperwork and see if I can find something. FRED OK, got my paperwork out. My scematic shows one plug with 6 pins, 5 being used. RED, SKY BLUE, LITE GREEN, and 2 BROWN. Unused pin matches up to BLACK in the mating plug. All one harness going into the controls. My 704 is at least 4 yrs. You have a good picture there but I am very color blind, Wife has to help me there, looks like you have all the wires. Am pretty baffles with that micro switch myself. My paperwork is number 704-28199-PO FRED

        Fred, thanks for the reply. I still haven't got this figured out. Please let me know if you find out anything more.

        Ron


        cousinabe, I can see where you might think that is the same drawing but I really don't think it is. The micro-switch on my harness doesn't appear to be showing in the drawing you refer to. Also the two switces shown in that drawing shaw a small 'stem' at the top of the switch to activate it when something comes in contact. My switch doesn't have that 'stem' it's just a tiny button.

        In addition the price for PN 10 is anbot $50. I know how expensive marine parts can be but I just can't inagine this switch being more than $5 - $10 ant the very most.

        Thanks for the info though. This really got me stumped.

          I am really digging deep on this one. Could it be a circuit breaker and the button is a reset? Reason I am thinking this is that the thumb switch works regardless of ignition switch position. This is only a light current control circuit with the big electricity going thru the relay. Is there a small hole by where the unit mounts in the binical control? One you could push a pen thru to reset the thing. Only thing I can think of. Maby the real YAMAHA guys will come up with something. regards FRED

            With a magnifing glass I can read that the switch was made in Japan by Matsu****a. The switch can be wired for either NO or NC. The wires are soldered in the NO position. There do not appear to be any reset provisions. The switches function appears to be to close the circuit when the tiny button is pushed in.

            I do not have control cables yet. I'm beginning to wonder if there is an attachment that may go on the cable to contact the switch button when the lever is in a particular position. I doubt it though because where the switch would be logically mounted it's pretty free of anything apparent coming in contact with the switch button to push it.

                Problem Solved

                seahorse, on another site, sent me an enlarged picture of the inside of a control box. It gave me enough confidence to insert the switch where I thought it should go. It easily snapped right into place and there is no other position it would fit without intereference.

                Now that it's in place I can see that a metal arm does swing and make contact with the switch button when the control arm is in the neutral position.

                Notice that on the drawing, the switch is held in place with 2 screws whereas mine is held in place with a plastic retainer/spring device. This device also hides a little more of what is exposed on the drawing.

                  So the tilt / trim only works when the engine is in neutral ? Sound a bit bazarre ! Think I would consider eliminating it real quick. What am I missing here? Anyone seen RODBOLT? FRED

                    The ENGINE is lockedout unless the control lever is in neutral. In other words the engine won't start in gear.

                      This is the trim switch. Has nothing to do with starting the motor. I trim my motors all the time when I am underway. Maby there was somekind of lawsuit that made YAMAHA come up with this set up. Am really mistified ! Where are the YAMAHA guys?? FRED

                          YEP, went back to the picture and followed the wires. 2 different systems using the same plug. Get thrown a curve when you cant tell the difference between black, brown, green, red. Ruins your prespective. Amazing that I fixed planes for years and could not tell if an instrument was in the red or green. Was a bit embarising when I would ask the stews or even passengers if an O2, fire or slide bottle was good or not. Wife is always telling me what colors flowers are. Dont have much of a problem with yellow and blue. Oh well, was told one time that dogs are color blind, that made me feel better. FRED
