Had to go back a look at a wire drawing to see what wire it was. The first time this happen i took the bike to my dealer. He remove the blue wire from the diode board and the amp draw we had showing on the meter was gone. It was not much but after a couple days not riding the voltage was low enough to not start. Have had this happen a couple of times in the 30 years I have had m R65 and R90. Have since upgraded to the 450 watt Omega system about six years ago.
