    I hooked up my head lights and tail lights and tried to test them for the first time since I owned this car (bought it as a shell). And realized that my dash lights are dimming slightly when my turn signal flashes. The car wasn't running while I tried this and Im missing the drivers side blinker bulb . Im sure this isn't normal. Could this be a loose ground ?

    Sounds like a possible faulty alternator.

    I agree with syderdrifter .. Take a multi meter and see what your battery reads ..Then start the car and see what the reading is.. If there is no difference you found the problem ..

    Well I have never quite heard it explained that way before ec17pse .. I`m amusing you mean , make sure there is a ground strap from the block to the frame . I just repair a lady`s car that had the same problem and this was the fix..

    For me and I’m sure a lot of other dsm’s too, I can hear my fuel pump lose power in and out as the flasher turned on and off. I used an additional 10 gauge wire from alternator to fuse box on top of the stock, the fuse box to battery and replaced both grounds from chassis and this fixed it. I also cleaned all the ground connections and my alternator is new.

    If the engine is not running its perfectly normal for that to happen, your using power when the flashers are on and the battery is dropping below 12v so the rest of the bulbs dim out that's all, when its running and its idling it can happen below 1000rpms also because the engine is using more power than the alternator at that speed can make.

    Ah, Widgmaster - guess you haven't been to the UK where they call ground an earth. Kind of like a hood is a bonnet, windshield is a windscreen, a people line is a queue, and soccer is football!
