    The factory radio/cassette player was recently replaced with a new
    Pioneer unit. I now have an apparent grounding problem that is driving
    me crazy. My fuel gauge now always shows dead empty when I know I have
    a full tank. When I turn my headlight switch on, I have no instrument
    cluster lights except the turn signal/emergency signal indicators,
    which just stay on. The high beam indicator works, but only when the
    headlight hi-beams are actually OFF. The speedometer doesn’t work, the
    factory clock stops, the temp gauge is dead. However, in daytime
    driving, those 3 items work, though the fuel gauge stays dead all the

    I’m not a D-I-Y’er, so a friend of mine who is experienced in
    installing aftermarket sound systems did it for me. He’s at a dead end
    at trying to troubleshoot this problem, even with my Bentley manual.
    ANY suggestions, advice, guidance, etc., are encouraged and welcome.

  2. You may want to check that the ground wire to the instrument panel has a
    good connection to chassis, including the wire itself and both end
    Best of luck!
