Any help would be great, thanks in advance.
Yes, either the 5volt regulator is not working, or the jumper is between 5volt and ground pin instead of 5volts and Vpu. Double check the jumpers. If you're able, the 5volt regulator is not difficult to replace, or you can ask for a replacement from your distributor.
I'm having a similar issue with the 5V failing, however, the 5V is just failing, connected to ADC or no. I checked the regulator, and it does appear to have 5V coming in, but nothing coming out (at least, it doesn't appear so, since the PSU can't seem to be turned on). Here is the output of W and i:
VREG too low, is there a short?

The output of the voltage regulator appears to be 1.5... I'm guess, just a shot in the dark here, but that's not supposed to be 1.5 for a 5.0v regulator? Anywhere else I can check for an issue (in case the regulator isn't the culprit)? If the regulator does need replacing, you mention contacting the distributor for a replacement regulator. I bought it here, but it looks like the board was supplied by SparkFun in my case? So contact them?
I doubled checked the output (without ADC connected) and it is 2.31... closer, but no cigarette.
Nope, that regulator is dead or a solder short somewhere. "W" command actually measures the output of the regulator to see if there is a problem and turns it off if the voltage reading is lover than a certain threshold. I'd say first check around the regulators to see if there are solder shorts, maybe probe with a multimeter to see if +5V is shorted to GND.
Yep, best bet is contact them. Or you can try repairing it yourself.
I bought 10 regulators ($3+ ... just the shipping was a killer, $4 on $3... ugh). The only thing I'm afraid of is that I replace the regulator and it goes again. Hence the reason I was wondering if there was a better place to check. I checked for a short and didn't see one. Don't know how quickly it would burn if it did short, but... I didn't see any shorts.
The regulator on the board may have been a bad one from the beginning: The self test is included for manufacturing test purposes as far as I know, so it should've caught the mistake but it didn't. You know, things happen.
