Title: Electrical problems..... Post by bikealarmblair on Mar 21st, 2006, 7:19am Hi all first post! My parents have a 98 (ish) 2.3 scorpio ultmia. Over the last few days the indicators/wipers have intermittantly packed up while driving then fixed themselves. Last night the car wouldn't start at all (no ignition lights, not cranking over) so I went & had a look for them. I found that @ the igniton switch the green ignition wire had 0volts on it so thought the contact had failed so decided to get the get the car going I'd bridge the green & black together but even apply voltage directly to it didnt bring the dash warning lights on. I've had a quick peek round the forum & see that water/damp fuse boxes are an issue (all covers are intact & on the surface they look dry) so guess thats my starting point. unless anyone has any other suggestion first? thanks Blair |

Title: Re: Electrical problems..... Post by Dave on Mar 21st, 2006, 9:47am Hi Blair, welcome to the site :) My first port of call in this situation would be the fuse boxes. As this failure seems to have occured over a few days I would check that all the fuses are clean and in their place properly. Try replacing any that look suspect. It may also be the case that the fuse box covers are not on correctly, the one on the drivers side can be a bit tricky to refit. If so then you need to check for any water damage. Also check the the large multiplug that goes to the drivers side fusebox is properly attached; it has 2 lugs that need seating before it is clipped into place or it will cause problems. See how you get on. HTH :) |

Title: Re: Electrical problems..... Post by Snoopy on Mar 21st, 2006, 5:23pm It does come out but needs some acrobatics from what I understand.... see here http://www.fordscorpio.co.uk/fusebox.htm But don't be put off a lot of people on here have completed this task and will no doubt tell you . |

Title: Re: Electrical problems..... Post by bikealarmblair on Mar 22nd, 2006, 2:50pm cheers although I rarely do nowdays I worked on car electrics fro many years so the fuse box shouldn't be too daunting if thats what it proves to be. can anyone confirm (cause I can't remember) if the green wires (at the switch) is an ignition live? |

Title: Re: Electrical problems..... Post by bikealarmblair on Mar 22nd, 2006, 4:02pm right its looking like the fuse box :( also found that ignition switch wasn't making contact with green ignition wire. |

Title: Re: Electrical problems..... Post by bikealarmblair on Mar 22nd, 2006, 4:37pm left hand (battery side ) fuse box stripped & its as dry as bone! not happy with one of the four pin relays so going to replace that before I strip the left hand fuse box. |

Title: Re: Electrical problems..... Post by bikealarmblair on Mar 22nd, 2006, 11:19pm does anybody have a wiring diagram? for the lights, indicators & front wipers. it seems that I've losing power to stuff thats on the steering colum maybe its all powered from the same relay? I've read that the indicator relay is near the ignition switch but I can't find it >:( |

Title: Re: Electrical problems..... Post by Simmo on Mar 23rd, 2006, 5:41am The wiring diagrams are here. It IS Scorpio although it says Sierra.http://www.carsoft.ru/avtorepair/sierra_el.html. |

Well there's that stuff as well, but I'm sure there was something else about the Ignition Lock relay and what it actually does. Maybe it was on the mail list instead :-/ |

Title: Re: Electrical problems..... Post by bikealarmblair on Mar 23rd, 2006, 7:06am thanks simmo (& snoopy) but unless I'm looking in the wrong place it doesn't show any components of the indicator system |

Title: Re: Electrical problems..... Post by Simmo on Mar 23rd, 2006, 7:22am Have you scrolled down to Hazard and direction indicators?. That shows the indicator relay in diagramatic form. I am sure someone on here must know its actual location.Have you looked behind the steering column shroud?.The scematic diagram seems to have it on the indicator unit. |

Title: Re: Electrical problems..... Post by bikealarmblair on Mar 25th, 2006, 11:30am right then I'm getting closer ;D it looks like my problem is the connection between the large multiplug & the main fuse box! I started testing the pins & each one had the correct signals so at first thought it was the loom but then did a pin to pin test & all were good :'( so I've lashed a little sub loom together & everything works ;D now unless anyone has any better ideas I'm going to get another connect & solder that in, if its not that then it'll be a fuse box swap! |
