Hey guys, I'm just finishing up my Ryca CS-1 project, and everything works except my neutral light. I found another thread that said the blue wire from my neutral switch should be grounded when in neutral, but my multimeter shows no change when I cycle through the gears. I checked the wire for breaks, but everything looks good all the way from the bulb to where the wire goes into the motor. My last thought was to take off the clutch case and replace the neutral switch, but I'm pretty sure I read somewhere that a faulty neutral switch was really rare, so I wanted to see if anyone had any other ideas before I go down that road.

Yup, grounding that wire makes the light turn on.

Yeah, that's what I was afraid of. I just put new oil in there! :'(

Check the wire closely. If it busted above where it exits the case you might avoid a hassle .

Get it in neutral and wiggle the wire.

Now that it's warm again, I drained the oil and discovered that the blue wire came un-soldered from the switch inside the crankcase. I took the switch out, cleaned it up, re-soldered it, and everything works fine now.
