07 R6 (sold)
09 R1






CODE: 46 on Yamaha r6.

So I bough this bike from a member on here. Great bike and rides well, but I was riding it the other day and all of a sudden, HEAD LIGHT CUT OFF, and the engine light came on, Bike rode just fine and shifted like no problem and after 10 seconds, lights came back on automatically but every since i have CODE 46 flashing every now and then. So does the CHECK ENGING LIGHT. It comes and goes, I don't feel any difference what so ever riding the bike.

Google suggested it could be anywhere from BATTERY, Rectifier or Fuel Injection System (Does have bazzaz hooked up).

Any suggestions or point of start?
Thank you all in advance.

I am starting off from the battery, will get that tested, though i don't feel, i would get much out of that. (It starts Fine every time)

Mine would throw the check engine light because of the butterfly valve in the exhaust. I pulled the cable to disable it and it hasn't come on since.

But, my headlight never cut off...

Sounds like some sort of loose connection. I would pull the gas thank, disconnect and clean all major connections in the harness, apply dielectric grease and re connect tightly.

Not sure how a battery would cause the headlight to just go out. Have you determined what code 46 is?

On the Yamaha FZ1 code 46 is a vehicle system power supply issue, so you may be right.

If you have a multimeter check running > 13.5v
Check it static +/-12

If it is less than 11.5 static get a new battery.

Did alittle digging for you, Its a general that usually appears when you have a rectifier issue or charging issue. so start with your rectifier by starting your bike and seeing if the voltage is >13.5 just like Jredford said. Your battery fully charged should be almost 13.1 or 13.2 volts. At 12volts a 12volt battery is dead so it should never be anywhere near that. Check all your connectors involving your charging system if your rectifier appears to be ok.

Hope this helps.
