I have a bike ray III working perfectly but there is something loose rattling around inside, sounds pretty solid. Took the lens off but what next? How do I get in to have a look?
I'm a little confused, are you calling the inductor a heat sink? ( the circle thingy with copper wire wound around it ). Anyway if you are, just to let you know that is part of the actual circuit. If that came off you have a big problem. If you can reattach it the way it came hopefully it will work. Cross your fingers.Okay, given the overwhelming response and now that the light has stopped working completely I will strip it down as best I can. So for others who may need to fix one of these here is what I found...
Do not remove lens and LEDs, no access this way!
Remove plastic switch cover, use some circlip pliers to slip into the two small notches and unscrew the back of the light.
Pull out the circuit board, by holding the sides of the switch and pulling firmly.
You have now disassembled the light and completely voided your warranty.
Congratulations, you are well on the way to being Australian, if you threw the instructions away without reading them you could probably apply for citizenship.
Anyhow... it is clear that the heat sink thingo was the rattle and now that it has broken off, no light. In the next installment I will try to solder it back on with a screwdriver heated up in the fire. I will then triumphantly use it for the 12hr next weekend.
Pics below for those who skipped school and can't read. Red lines show where the heat sink was connected.
Ace!....always good when things work out.Inductor (thanks for the heads up on the nomenclature) is now re-soldered to circuit board and behold, there is light.
Whilst I respect the commitment that a lifetime warranty represents, (I do own two Cannondales) you just can't beat a bit of impromptu shed time with no clue and a soldering iron.
