1v8 led not lighting.

Hi Kite,
I received my Circuit Sword, many thanks for that.
I am going through the basic sanity check.
So, I plug in the USB power, press the power button on the board and the 1v8 LED doesn't light up, the rest of them do.
I grab out the multimeter and I check the 1v8 meter point and I get a reading of 1.77v.
I don't know what to do next.

Hi,
That sounds ok, continue onwards! It is likely that either the diode is bad or it's missing a tiny bit of solder. 1.77v is well within spec
let me know if there are other issues and we'll debug further!

Thanks Kite,
I have gone ahead with the rest of the testing, it works fine.
I have almost finished by build, just putting the 2 halves of the shell together when I have found that the cable for the fan is about 5mm too short.......
I mounted the fan in the cartridge to act like a blower to pull the air out through the heatsink, but it is just that tiny bit too short.
Do you know of an extension cable that I could get for it? Or what JST plug it is?

Good to know, and good for checking before
glad it's all ok!
It's an obscure connector, there aren't extensions for it.. you have two options:
a. Cut the cable, and extend the wires while keeping the connector (probably use some really thin/flexible wire)
b. Cut the cable and add your own JST and solder to the CSO on the solder pads next to the connector (labelled + and - , these are for the fan)
