We have a 1970 250 2.5L 6 Cyl.

Runs really nice but has aa few issues I'd like to sort out, first on the list being the turn signals.

All lights work, dash and the signals, but all we ever get is a fast click, so we're just manually tapping the lever for now.

Just wondering where to start looking. I assume it;s either a ground or a clicker issue? As I said, the lights seem to work fine so I'm ruling out a bulb issue.
