    Challenge: dash - strange electrical issue

    AU3 Falcon. Not a wagon, not on gas. Perhaps this is the issue.

    Now, primarily when accelerating at 'higher' revs (eg. hitting 4k up an onramp) my dash drops out. The result varies considerably - gauges jam in random positions, start doing double or half readings, spinning backwards, fuel light and temp light come on, etc. This doesn't stop until the battery is disconnected from the car.

    This had me thinking I needed a new cluster because something was corroded or broken but then the other day it happened and my stereo also joined the party with the volume stuck continually increasing. Nick mentioned it was probably actually the steering wheel controls rather than the stereo itself... which thinking about it makes a lot of sense.

    So what am I looking for exactly? A funky earth that is shared by both the dash and volume control knobs? What about the fact that it doesn't change until the battery is disconnected? That's f'n odd.

    First thing I'd do is check that your alternator is regulating properly. If it's shooting up to 18v+ when the engine is revved then that could explain the instruments and stereo shitting themselves.

    Interesting thought.

    I did check it a while ago and it was fine - after I'd had a flat battery from leaving the lights on - but maybe worth another check at high rpm.
