74 scamp, no turn signals. All other lights work.

I have power at the fuse link. I have power at the bulk head connector. And I have power to the ammeter. But no power anywhere else. That ammeter controls the power to the rest of the car correct?
As built, everything goes thru the Amp meter. Simple to bypass, just put both wires on the one side, or bolt them together, with a small stove bolt, and insulate it well.

EDIT: both wires on the amp meter. Tie them together. You might have other problems, like a dead short to ground. Have a Volt ohm meter?
