2004 wr450 lighting issue
Posted January 28, 2013 - 09:17 AM
Anyone that can help. I have a 2004 wr450f and put her away for the winter all good.
Decided I should get her out today and give a once over ready for the better weather.
Once I finally got her started I realised I had no lights working except the ignition led.
I charged the battery but that was fine anyway. Now im definitely not an electrical guru.
Could anybody shed some light my way as too what a rectifier, stator, lighting coil does
As id like to understand how it all works I.e why lights only work with engine running etc.
I must figure out my lighting issue as I wanna do abit off greenlaning.
Many thanks for looking.

Chances are, if you get the bike running and you hook up a volt meter to the two pins on the headlight connector (AC measurement scale), you'll see around 12 vAC at idle, and as soon as you raise the throttle, it'll jump to somewhere near 24 vAC. This is a good indication that your voltage regulator is unserviceable. If you hook up the volt meter with the bike running and there isn't any voltage, then your coil has gone bad or you've got an open (broken wire) somewhere in the system.
Hopefully this helps you out.
