Thanks Joe! How would a left turn signal be actuated? I would think that if there's no need for the phase, you'd need to cycle the cam through it without actually cycling the left turn indications.


Can't really do that because it is the same cams coming around each cycle. If there were enough circuits you could have two cams for each circuit and a bunch of relay contacts to select which will get tied to the lamps. With mechanicals you can change the timing of the indications but you can't change the sequence of them.

Where did you find a copy so fast?

I won mine on ebay and then Joe went out and found a copy based on missing the ebay one.
