2007 BF150 dual batteries. I'm a dumb ass. Crossed my battery wires and turned on selector switch. Installed new switch. Had batteries charged and tested both good. Cleaned connections. Checked all fuses and all good. Turned on batteries and all electronics work. Turned key on and gauges work but nothing no lights or beeps but when turning key off the usual roaring sound is heard which always happens when shutting down and I'm told is normal.
Any help is much appreciated
