Have 86 Nautique. Just completed removal of the engine and getting block welded due to freezing situation.
Every component was removed from the engine and engine removed. I reinstalled the engine which went well. Now I have no power to dash. When you turn the ignition nothing happens. No gauge movement at all. You can short across sol. and turn the starter over. The main circuit breaker on engine rear is on. Where is the best place to look for the problem? |

Just went thru complete removal of engine and had cracked block repaired. Put engine back in boat
however I now cannot get any power to starter or dash. Battery is connected to solenoid. All wiring seems to be properly installed. No power to ig. switch or anything in dash. You can short the solenoid and turn the starter over. Any ideas on how to chase down the fault. |

I think it is an oarnge wire by the engine that is your positive to the dash.
But.... First thing I would do is get an ohm meter and make sure you have a ground at the dash. Tim |

Red wire usually from the battery side of the start relay (solenoid) forward through the 20amp breaker to the ignition switch would be a good place to start. Orange will be after the ignition switch. A lack of a ground will affect the stuff that's feed off the dash but not the start relay. It gets it's ground off the engine block so I'd say you have a main power feed problem. Check the wiring harness rubber plugs/connectors. They can get quite burnt up inside from corrosion.

I will check to see if there is power in that breaker in the dash. That breaker is suspect due to
the fact is pushes and disengages somewhat different that the other beakers in that row. This power problem appeared somewhat prior to the engine re-build . This indicates this electrical problem existed prior to the engine tear-down and very well could be a faulty ign. breaker. r.p. |

Thanks the red wire is the one going to dash power brkr. My problem
was so obvious i couldn't see it. I had the red wire connected to the wrong side of the Solenoid. Kind of a catch 22 could not turn solenoid on with no power and the power req'd was on the wrong post. Switched them bingo. r.p. |

Robert,
Glad it turned out to be so simple. Yeh, it was one of those "forest through the trees" scenarios!! Oh, the different"feel" to the ign breaker is most likely due to it being a higher amp rating than the others. More spring behind it. |
