can someone help me understand what kind of "R" fuse these ASICMINER block erupter blade V2 boards take? Apparently mine is blown, or at least I'm willing to try to replace it to see if I can finally get it working for the first time. I just got these boards new, and they didn't work out of the box. I heard a lot of rumors about their fuses being really crappy. Any help?

are the version 2 blades 10a, 15a, 20a even? I can't find ANYTHING for documentation on these boards. ASICMINER blades suck man, unless you can get them working. ANNOYING! Also, can i use just ANY 10a, 15a, 20a fuse on this board (of course, it would be according which ever number of amps the original "R" fuse is supposed to be)

The "R" fuse is 8A rated. The blue-board Blades came stock with 10A fuses, at least all the ones I've seen. I'd replace with a 10A SMD fuse, I believe package size 2410. It shouldn't take much forum searching to find several relevant links to parts suppliers for a replacement.

Have you tested the fuse for continuity? Use an ohm meter to read out, or a continuity tester, heck even a low-voltage battery and LED. It's riskier but you can also short around the fuse with a paperclip or something temporarily to see if that powers it up.

i got them working with a 10a automotive fuse. but i went ahead and ordered the good ones just in case.

You should be able to get those black fuseholders from Radio Shack and solder one in parallel to the old fuseholder if all else fails, and those glass fuses are readily available. I'd choose one rated at lower voltage (not the 240v ones) and also slow-blow 10 amp (those usually have a coil inside instead of just a wire). I have a box full of the fuseholders like that, I'd sell them for 50 cents each. plus postage, even include a fuse if I have any that are the right value.
