[Mgs] 1958 MGA

[dave northrup]

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

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