    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.

    Your charging system is being overloaded at tick over
    if you raise the tick over speed slightly then it may help
    the faster the engine turns the faster the charging system rotates and the more power it produces

    Thank You for your help. When you say tick over speed do you mean raise the idle?

    Battery is new, Thanks

    Using an external high quality meter, what is the voltage across the battery when the RPM is at 2,000. What is the voltage across the battery at Idle. What is your idle RPM.

    In Hobbits' case, that would be an affirmative...:newsmile075: just yelling a little louder to get the post to 'cross the pond...:D
