I repaired a Nissan Maxima that the local Auto Zone connected a battery in reverse to and the bill ran over $2500.00. It killed damn near everything. |

If my memory serves me right from years ago when I was in the automotive parts industry, Alt light on when key off indicates blow diode - alt rebuild might be cure...diode is a one-way gate, reverse polarity may kill them |

Is there a line fuse behind the radio? I wouldnt assume major damage as of yet. While you were hooked up backwards, It seems to me and what I know of direct current that the fuses and relays should of took the abuse. The clock for instance should of simply ran backwards. The radio is either fused from behind or it could be one of those capacitors ((usually 1uf) that they put in the circuit for interference.Car starts. Good. Make list of what dont work from there. start with gauges. I dont see the gauges themselves being damaged. a lot of 12vdc equipment is reversed by switching polarity. A lot doesnt care either way. lights,clocks,motors,etc. The alternator would be an exception. But I dont know if it isnt the battery that is bad. Try other battery that is know good and fully charged. rule out all easy fixes regardless of how rudimentary.Keep posting effects of each fix. |

All fuses appear to be ok. Why does the alternator warning light go off when the engine is running and when the ignition os off, the light comes on??? Roger B. Changing thread to: '80 308 GTSi Battery Mis-connection! |

Start by checking ALL fuses. You are probably going to have to get the Alternator rebuilt to start with and provided there are no blown fuses to the items that do not work, they will have to be replaced also. I hate it for you. |

I reversed the position of the battery and reconnected it(Positive terminal on the driver's side) and the engine fired up after a few tries, but the fuel gauge and oil pressure gauge don't work so I shut it down because I didn't know what the oil press. was doing. So at this stage, the radio doesn't work, the afore mentioned gauges don't work and the alternator warning light stays on after I turn the ignition OFF. All the fuses are ok, but I obviously damaged something in the electrical system by hooking the battery up backwards, so I need some help to figure this out. Thanks, Roger B. |

Wonderful-I just checked the owners manual on p. 58 and the diagram shows the Positive terminal on the passenger side and thats the way I connected it. I then checked the wiring diagram on p. 109 and it shows the opposite, so it appears to me that I made a big mistake and what do I do from here on? I again checked one of the plugs, dry and clean and when grounding the plug wire and cranking it over there was no spark so I obviously have toasted some stuff. HELP!! Roger B. |

If you have grounded the positive wire your fuel pump is running in reverse. You may have damaged a lot of electrical items. |

Checked everything again-radio and clock don't work. All other components seem to work ok, however I pulled #4 plug and it was dry. Also, when the pump is running it makes a hissing sound like some sort of air leak. All the fuses are also ok. Roger B. |

Roger -- What year/model/version 308? -- add it to your Profile.
"positive ground"? -- I'm fairly sure it's not. |

If your clock is no longer working you may have blown a fuse... pull the cover and check your fuseblock. |

I retraced my steps and everything is in order. I had installed a new ground cable of the same gauge and a negative connector and a new battery. When I connected the battery I failed to remember it was a positive ground and I connected the positive first, then the negative. Is it possible I did some damage to something electrical in the system???? The lights, horn, etc. work(the clock doesn't work-it used to), but everything else is fine. I haven't worked on it the last couple of days, but I will today so any suggestions will be helpful. Thanks, Roger B. |

Pull the plugs and check for raw gas. Then check your plug wires to make sure you have fire to the plugs. If you have both you should have some sort of ignition. |

Assuming you did not touch anything else, let the pump work for a few minutes to prime the line and the carburetors and build up pressure. And it should fire.
I would go back over the work once more to make sure that you have fuel to the system, spark to the plugs, and correct timing. |

Just finished installing new a/c lines, fuel lines, etal and the engine won't start. I can hear the fuel pump working(which I never heard before). Should I just let it pump for say 5 min. or is there something else I'm missing here. Sorry Bruno!! Roger B. |
