I am installing a original 1970? kohler engine back into a 1970? trail boss 6x6. I need to know witch of the three wires go to voltage regulator, what voltage reg. I need and a diagram to to install. The engine is a 1970 kohler, two-cycle,one cylinder fan cooled with electric start. All I have is a complet entine with the wires comming out of block cut off.One wire gose to the coil and I have one red and two yellow that are cut. I can handle the starting circuit with no trouble, but need help with the charging circuit. thanks. |

the two yellow are for charging, they go to a rectifyer that has 5 amp fuzes for each of them, if you cant get one from richard clark maybe you can make on from 4 diods that can take 5 amps at between 10 to 20 volts say, that shold cover it, just set it up as bridge rectifyer and itl make the yellow charging curent into dc volts for charging circut output side of rectifyer,
just ask at raido shack and they can show you how to put them together as a bridge rectifyer.
dont worry about controling votage as your
engine wont put out enoph to hurt battery,
at full speed your kholar will do little more than trickle charge it anyhoot!
now as to the red one? it must be your grd as you have one more colored wire comeing out of engine to coil rigt?
your engine will run without any other conections made exept the coil wire from the inside of engine and other side of coil to grd
however the charging coil stator plate and vehicle sholde be conected as a comon ground for charging to take place, you have a wire from your engine that go's to coil, there shold be another wire on the same post to ground and shut down engine, it would continue to starter switch so it can be grounded when key is in off position, starter switch needs a ground, also has a wire from batery that it farwards to starter relay for controle of starter only, and batery can be forwarded to lights as well,
YOU NEVER NEVER ADD BATTERY+ POWER TO THE ENGINE!
NOT TOO THE COIL! NOT TO THE POINTS!AND NOT TO THE STATOR (YELLOW)WIRES!!ONLY THE RECTIFYER OUTPUT CAN LINK TO BATERY+
the power in or points side of coil can be grounded when stoping engine.
the - side of rectifyer should be grounded. |

The standard rectifier that is used on smowmobiles is not a bridge rectifier but is a half wave rectifier. Take an ohm meter and test continuity between either yellow lead and ground. If there is continuity to ground than you need the snowmobile type half wave rectifier. If there is no continuity to ground from either yellow leads, than you need a bridge rectifier. You should always have continuity between both yellow leads(very low resistance, it's a coil) My JLO's need a half wave rectifier and my Cuyuna needs a bridge rectifier. I can explain farther if needed. |

We have to find out what a bridge rectifier actually is and how we can make one for a school science project. Can you offer a web site or we we could get this information, remembering that we are not use to the terminology, so the easier the better. thanks so much. |

http://www.howstuffworks.com/index.htm You can make a bridge rectifier with 4 diodes or you can buy a bridge rectifier block from Radio Shack. Either method will work on a snowmobile engine with 2 wires for the charging system. Actually the bridge rectifier will work better than the factory rectifier. |

ooh my god! jude your teachers should be able to draw you a diagram, its simple realy, dose your schoole have an electronics class? any library should have info for basic electronics,
a bridge rectifyer is simply 4 diods atached together in a dimond shape, diods alow electricle current to pass only in one direction,
so they are arainged so 2 leads are for ac input and 2 leads are your rectifyed dc output.
each diode is laybled with a little line wich tells you wich direction the current can pass, you arainge them so there are 2 lines together at one point,2 lines on oposet sides of diods with that oposet side together at a point, then atache the 2 open ends of each pair to form a dimond with this newly formed set of points haveing a line end and oposet end from a line , this set with one each type are your ac input's each remaining point are ether line ends or oposet from line ends, these are your dc outputs,
i remember this stuff from high school myself,
but thats was in the 1970's |
