Hello from Savanah Ga.....
I have randomly seen this charger go up to 15 Volts and slowly drop back down ....not sure why...and I of course receive "High Voltage Alarms" (set at 14.6)
I understand that AGM batteries are sensitive to being over charged so I was reading up on this...and the 15 volts was concerning....
Thanks for any suggestions....I installed this 2 weeks ago and am still learning..
I attached schematics for refence.
