i need some help. have a 1948 MGTC with add on signal lights.  the red light
indicator on the dash only lights once when signal switch is thrown either
direction. an audible buzzer hooked up to the flasher only beeps once at the
same time as the lights flash.  could it be the flasher that is bad.  signal
lights work fine.. healeymanjim
