Good Morning Texicans. Well changed the battery in the truck yesterday. Sheesh they don't make it easy. So loaded up to day and got halfway there and alternator starts acting up. So no shooting , again. Taking it in Tuesday so next shoot day is maybe Wednesday. Otherwise it is a fine day.
Oof. Yeah, alternators and batteries are in kind of a symbiotic relationship. A bad battery can kill a good alternator by causing it to overwork itself, and a bad alternator will kill a good battery by over or undercharging.
Guessing your truck is a Chevy or a Ram by the "sure don't make it easy" comment? Wasn't a huge fan of replacing batteries on either make. GM and Chrysler really take battery placement to the "oh, shit, we designed the car and didn't give a good spot for the battery, where can we jam this mother?" zone. Eurotrash cars are similar, as are mid 2000s-onward Ford sedans and compact SUV's, save for a handful of models.
Hadn't had to work on a newer Ford truck, so I can't comment on battery placement - but my mid 2000's Ford work truck was stupid easy to get to the important bits.
