GL1200 turn signal flasher BUZZZZ

When I activate my turn signals they light up but won't blink, The flasher is just buzzing, Now remember I've taken of all the goldwing acsesorys fering, bags, everything. I installed after market LED front turn signals and a combination LED tail, brake, turn, license plate light, Is my flasher bad, or do I need to get a universal LED flasher? Another thing how much compression should my 84 1200 have? Like I said before the left side has spark but it's dead, the pipes on the left are cold, If the seafoam I loaded the cabs up through the fuel pump does not work, then i need to check the compression, if it's good then i guess the carbs need looked at, if compression is bad, does that mean head gasket? I changed the oil and it was clean, no coolant in oil and no oil in coolant.
