Ammeter

[deerbuster]

I have a 1968 F100 and my ammeter shows just a little above half while running, but when i put a turn signal on, it jumps between middle and clear to the C. Only with turn signals. All bulbs are good, new battery, alternator and regulator. With it jumping i can turn on the headlights and they dont flicker or dim. What am i missing?
Thanks

I think you have a ground ghost that will require checking all ground straps. You may also want to try using a jumper cable from the body to negative post of battery and try your signals then.

Thank you. Ill try tomorrow.
