I just built the motherboard for my Ambika kit, and the “test” stage fails… i.e. I have no power. The power supply works with a different Ambika, and I checked for the things obvious to me: shorts, wrong polarity on caps and diodes, forgotten solder joints… what could be going wrong?
do you have the power header jumpered?
check your inbox btw
check for continuity between all the power rails and ground (at the regulators is easiest)
OH GOD PLEASE SHOOT ME
The problem was a not-switched-on wall strip. Sorry for that.
Can someone please delete this thread? This is embarrassing… Thanks altitude for your help
