    Yup. A little trash jams the impeller and gives weird readings. Just have to verify everything. Even a stick is wrong if you park on a slope!

    Once again, an open circuit on one of the small wires will not result in a negative current reading only a zero current flow. Both of the small sense wires need to be connected in order to have any...

    The OP conditions were normal voltage indication and negative current flow.

    A high resistance connection will only produce a low current indication. It has to be a reverse polarity condition in order to have a negative current flow indication.
  7. Doesn't matter. For a shunt to cause a negative...

    Doesn't matter. For a shunt to cause a negative reading of current flow, the current flow would have to reverse. This is the only way the sense wires will read a negative flow.

    An ammeter is a passive instrument. It cannot reverse a signal. Yes it can indicate a negative (reverse) current flow but only if the polarity on the sense wires was reversed.

    If that were the case, how would the ammeter ever read zero?

    If an intermittent connection, it would vary from the correct reading to zero, not into the negative range.

    Another way to look at it. Take the shunt as in #56. Put your voltmeter leads on the screw terminals with the red rings. You will read a very small voltage while current is flowing through the shunt....

    Look at the shunt in #56 and imagine it intact, without the burnt spot. The gauge senses current through the two small wires that have the red ring terminals. The reason for the shunt to exist is...

    I don't agree. Current flow indication is a function of the small voltage drop measured between the terminals of the shunt. A broken wire = no voltage drop. And no voltage drop means a zero...

    Ok. Here's why it's a bad idea to use automotive alternators with built in regs, in aircraft.

    The regulator picks off power from the output of the alternator. The controlling element of the...

    Tip on torque adapters: if the torque wrench is 90* to the adapter, no math is needed. When I fabricate an adapter, I make sure that the square drive allows this. Makes life easier.
