    When I have my turn signal on the voltage gauge on the dash moves. I clamped an ammeter on the alternator and it will jump 5 amps when the turn signal light is on.

    Is this normal or a sign of another problem lurking in the wire looms?

    how much is it moving? 5 amps doesn't sound too bad. I'm pretty sure your fuse is rated for 10.
    It could be a sign of either a dying battery or a weakening charging system.

    Or it could be that it's always done it and you jus now noticed it.

    5 amps is just about right for two bulbs.

    The gauges in those trucks would move when you just think about turning the headlights on.
