Sunday- leaving on vacation and LR4 won’t start- cycles through many test.. gages all crazy etc. Replaced battery as the voltage showed 8.2 on Gap Tool. All worked fine to get us to location 2 hour drive towing a trailer. Now doing to checks with Gap Tool - Voltage is never above 13.2 (all very slow campground driving) I always though I was about 14v before Is this normal- I did put the battery on a charger as it may just need a good really charge anyways? I did do the battery reset have no update the type of battery yet using Gap Thoughts of being normal or am I on my way to a alternator change?
