after sking tonite ,the wires above the regulator got blackened and the aluminium housing itself melted??? i got it home ,,,,but the charging system read 12.2 12.1 with no electronics on and 11.9 11.8 with the nav lights on,, i have many acc. hooked up to the system but never run them at the same time?? any ideas why this would melt down?
