I hit a hole last summer... Volt gauge went to FULL charge... Cured itself, I thought.. It happened off and on 4 or 5 times THen went to FULL discharge 2 weeks ago... Turned out to be a Voltage Regulator.. Now I am hearing other guys having the same problem.. 2012's seem to be the worse... There was a recall on them back then.. So if this pops up to you, you might want to checkcthe Voltage regulator first
