Hello everyone ! I am a newbee here at the Forum. I have a 1991 FLHTC my problem is that the volt meter gauge fluctuates from 10 volts to 12 volts when the signals are put on. Also sometimes the radio cuts off and the signal light indicator stays solid for a couple of seconds then indicator will blink and the radio will return to normal. It never seems to happen when driving at any speed but only when the bike is at idle, or with engine off. Any suggestions? Thanks in Advance.
