    Default 504 Petrol gauge Erratic swinging from Empty - Full - etc

    The petrol gauge on my 504 has just started intermittently flicking from full empty to full full (so to speak) - that is - way past its normal "full" position (and the tank is full - filled it up a day or so ago). No obvious cause - eg going over bumps. Never notice this before. The gauge has otherwise behaved itself for the last 35 or so years!

    Any suggestion as to where to start looking for the problem, and hopefully, a solution?

    Replace the tank sender.

    Pull the sender and see if the float hasn't self-destructed.

    Ive had this before too. The Auto electrician earthed the guage and cluster to the steering column (or some close by metal) via an additional wire. Problem solved.

    Ive got a brand new 504 tank sender unit if you cant find one in Melbourne. They may be no longer available.

    My fuel gauge jumps around depending on acceleration/braking. I thought this was normal...

    In the sender unit, there is a small card with resistance wire wound around it, and an arm which moves on top of this. When they get old, the windings bunch up, and this may be the cause of jumping around.
    I've often wondered if it might be possible to correct this by taking it apart and re-winding it, sticking the wire onto the card with superglue or fibreglass. I wouldn't want to stuff it up though....the pressure on the little arm probably needs to be exact....otherwise it will either not connect, or press down too hard, wearing out the windings.

    Thanks Ian

    I'll trace the earth - I realise that I've been too lazy over many years to actually put in the two bolts holding the instrument cluster to the dash. Taken the thing on and out too many times to bother......Serve me right, perhaps

    I'll try to look into it.
