Title: A65 electrics
Post by: Gordonh on 13 Nov, 2020, 12:18
Hello all,I am ignorant in the field of electrics,my A65 Hornet has no lights at all,it has no battery but runs fine.It has a Boyer power box which I believe is a single phase,however the label from the power box has gone,it has two wires going to the alternator.My bike also has a Boyer electronic ignition.As I say it runs really well.The only thing is that it is a positive earth.Can it be changed to negative earth. It has no other electrics other than coils, alternator and Boyer power box and ignition it's just that I keep getting the earth mixed up as I am used to negative earth thanks,Gordon.
