Most likely a poblem with the flasher unit going power on okay, but 
not flashing.

If you have ane original type thermal flaher ubnit, and you installed 
any LED bulbs for brake lights or front turn signaals, then it will 
not work.  A therrmal flasher unit will not flash unless it sees the 
electrical load of two 21-watt incandescent lanps. Solutiobn then is 
to change to a heavy duty thermal flasher, as is used for 4-way 
hazard flashers, or to install an electronic flasher unit that will 
work with the low power LEDs.

As usual, Barney was right.  I happen to be working on a 58 TR3A, and the flasher units are the same.  I guess its ok that I'm now running a Triumph flasher unit in my MGA????

The one that failed was purchased from a FLAPS last year.  The one from the TR3A may be original; that car has been off the road since around 1972
