Guy's, Just put my engine back in my boat and took it out yesterday. Runs great in the driveway. took her out yesterday for the first time. Everything is going good for about 15 minutes and it just died. I lifted motor box and wiggled all of the wires and nothing. did it again and she fired up. Took it home and ran it at the pier for awhile and all good. Went out for another ride and she died again. Got her started again and put her on the lift. I ran it there for about 30 minutes and reached down and touched the coil and it was to hot to keep my fingers on. The engine temp was at 143. My tach was not working were I found the gray wire had not been hooked up. My questions are 1. Should a coil ever get so hot that you cant touch it? 2. Would the gray wire that runs from the neg. post on the coil to the dash make the coil overheat if it was not hooked up? ------------- 83Ski |

1) No Is the coil layed down or at least on an angle. (horizontal will make an oil filled coil over heat) 2) Not sure, is the gray wire for the tach? If so then no. What about the ballist resistor? It should have 12v to the coil when cranking then drop back to 7/8 volts when the engine is running. 12v to the coil with the key in "run" the run position will get the coil to hot to touch. ------------- - waterdog - http://www.correctcraftfan.com/diaries/details.asp?ID=3896&sort=&pagenum=2&yrstart=1978&yrend=1978" rel="nofollow - 78 Ski Tique |

the coil is horizontal but that is how it has always been. the gray wire does go to the tach. ------------- 83Ski |

Don may not have the ballast resistor by pass when cranking on the 83 ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| Did you make any other changes to the wiring or ignition when you were re-installing the engine? Is the coil oil filled? |

No changes that I am aware of. Dont know about the coil. I will look at it tonight. It is the same coil that I have been running for the last two years. ------------- 83Ski |

Coil doesn’t tell me much. I wrote down all of the writing off of the coil and googled it but it led to nothing. (IT WAS MADE IN CHINA)Looked at the wiring compared to old pictures that I had taken and wiring diagrams from CCFan and it all looks good. I discovered that my distributer cap gasket has deteriorated. i am going to order a new one. ------------- 83Ski |

Even though the water temp reads 143 the coil is going to get pretty warm. Next time your out put your hand on the air intake the coil is most likely going to be the same temp. Mike ------------- Lakedog55 |

Double check that the ballast resistor is getting 12v on the in side and it should only be putting out around 9v to the coil. My coil did this when I wired the electronic conversion the way the directions said to.(jumping the ballast resistor giving the coil 12v) Ended up that I had to run it through the ballast resistor then everything was fine. |

Thanks for the advise guys. I took it out yesterday for about 30 minutes and she ran perfect. I installed a new gasket on the distributer cap and cleaned off all of the metal spots inside the cap. I didnt really have much time because it was getting dark. ------------- 83Ski |

Is it necessary to use a ballast resistor if you are running a newer coil? The guy at the local marine shop that had worked on my boat for the PO said it wasn't necessary, that I could jump the purple and red wires together. That made no sense to me. I ordered a ballast resistor this morning from whitelake. ------------- '02 Ski Nautique 196 w/ 5.7 Apex bowtie - Sold '87 Barefoot - sold '97 Super Sport Nautique - originally custom built for Walt Meloon '97 Ski Nautique '83 SN 2001 |

Bret it does not matter how new or old the coil is.It does matter what the coil manufacturer says to use ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Exactly! If the coil is internally resisted or needs the external ballast resistor. If you run a point set or have a EI conversion will also make a difference. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I'll have to take a look tonight and report back. ------------- '02 Ski Nautique 196 w/ 5.7 Apex bowtie - Sold '87 Barefoot - sold '97 Super Sport Nautique - originally custom built for Walt Meloon '97 Ski Nautique '83 SN 2001 |
