My experience is that flashers will also click rapidly if one or more of the turn-signal bulbs is burned-out (or in the case of Alfas, not making decent connection due to corrosion or just poor sockets). I was unaware that short circuits will also cause it...

Instead of a relatively steady click the unit puts
out a rapid click and the lights no longer flash.
What would cause this?

A rapid click indicates that the flasher unit is overloaded. That could either happen through a bulb that has failed and shorted internally, or by a wiring problem (a wire rubs through and shorts to ground) or by an internal short in the flasher unit itself. If this only happens on one side, look for a bad bulb. If it happens on both sides, it's probably the flasher unit.
