    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Yea, my C40 has 3 pulsers coils one for each cylinder. that makes more sense than all this other stuff added to mystify the way things work. So if that C85 has 2 pulser coils should that mean #1 is run off of one and #3 run of the other, since swapping the brown and blue wire makes the miss...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    probably at work back before 2006, but I did not create much with it I am surprised to see just one pulser coil on that 90

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    I missed it earlier, seems he just swapped the brown and blue wires from stater to CDI. red stayed the same I have no idea what those 3 wires are from. charge coils or maybe charge and pulser coils looking at a parts drawing/pic the stator seems to have 2 charge coils and 8 lighting coils...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    just for your information, the lighting coil feeds the rectifier/regulator to charge the battery. charge coil feeds into the CDI to charge up the capacitor for ignition system and so does the 2 pulser coils

    Boscoe, you know anything about a C85 ingition system? should it be the same as a 90 about that year?

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    all I can say is good luck. I have never read anything like that before in a Yamaha Service manual. the 90 should be the same as the 85 in my thoughts. and it fires plug #1 off of one pulser and #3 off of the other pulser coil #2 is made up by the CDI . peak voltage readings need to be taken...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    are you saying there in no spark on #1 cylinder? how did you test the spark? did you check the peak voltages into and out of the CDI with the proper test equipment, and compare those reading to the specs in the service manual for your motor? it was my understanding that #1 and #3 get the...

    low compression #2 cylinder - 1988 suzuki dt85

    take it apart to see what all is in need of replacing, then decide if it is worth try to repair it. It is just your time that it is costing you

    Yamaha runs awesome, will not re-start after running???

    the more fuel you burn the more heat is generated, so if the cooling system is not working well it can cause more heating while running high RPM

    Yamaha runs awesome, will not re-start after running???

    you can always pull the stat and test it in a pot of water to see if it opens and closed at the correct temperatures to see if that is a problem. or buy a new one and hope that was the problem. It is not normal for the telltale to be real hot on 2 strokes, but I know very little on 4 stroke...

    Yamaha runs awesome, will not re-start after running???

    well, no start means no spark at proper time once heated up, bad compression when heated up, not enough fuel or too much fuel when heated up. spark and compression should be easy to check, but the correct ratio of fuel to air is not that easy. so, Bosco mentions adding more air by opening up the...

    Yamaha 150 ProV? Yay or Nay?

    very true, but you need to know which color wires do what for the different brand motors. steering, shifting, and throttle I am not sure of on different brands/makes

    Low spark on 2003 25hp

    need to know what peak voltage is going into the CDI and back out. special meter or regulare meter with a DVA adapter to take readings

    Low spark on 2003 25hp

    do you any idea what motor you are talking about? We sure don't. Make and model info helps a lot. but with that said yes you can test the peak voltage inputs to and out puts of the CDI, and compare them to the specs in your service manual for that motor. it has procedures and specs

    I am sure the bolt hole pattern for mounting outboard motor to a boat have been standardized, so you would not have to drill ne holes to mound a different motor
