So hooked up stereo and underdash gauges, turn ignition to ON volt meter was reading 12v, stereo wouldnt turn on. Packed it up for night. Went back out today, checked the 1A in line fuse (looks good) checked fuse box all look good. Checked 20200629_183742.jpg grounds, tight and on clean metal.Turn key back to On... voltmeter no longer reading and still no stereo. Any thoughts? Not sure where to look...heres what I did wiring wise..what am I missing?
