First check that the gauge supply voltage is correct (10v +/- 0.5v).  Low
voltage can cause the light to flash.  Assuming that's not it, if the light
flashes *with the 43 module removed* then it's unquestionably the
gauge.  Also, if the 43 module is taller than wide and the light flashes
without also pegging the needle, it's the gauge (or low gauge
voltage).  You can generally fix the gauge by removing the face, removing
the circuit board and replacing the electrolytic cap on the board,
preferably with a tantalum.  But it's a nuisance.
