[QUOTE="Bean67, post: 1428655, member: 27259"] Hey I used the load tester at my work I believe it is an auto meter i selected the proper digital settings and it came back both batteries at 12.6 100% charge with 550cca for the lowest Value. So far last couple of days no battery light and voltage has stayed at 14.3-14.5 so not sure can't really test it with the system working properly and not able to duplicate issue but I guess I'll just keep running it and if it happens again either see if I can check it or just replace battieres. Not sure what would cause voltage to drop to 13.8 besides something like a regulator which means replacing an alternator. [/QUOTE]
