I have added indicators to my 12v 51 plunger A10. I have recently noticed that when I reconnect the earth wire from the battery the indicator unit makes a noise that seems to suggest that it is energised. Is this correct? I assume it will be gently draining the battery and may be leading to the need to frequently replace the fuse.
i am considering installing a switch to enable me to turn the live conact to the indicator unit off when i complete a ride.
