My battery is low on my Tahoe and would like to use a battery charger to get back to it's full charge. I never had to charge a NNBS trucks battery yet and am wondering if I have to be careful so I don't mess up any of the electronics. On other trucks I never unhooked the battery from the truck and I just hooked the charger to the battery cables on the post. Would this be ok to do on my Tahoe also? I know it is probably a stupid question but I don't want to mess anything up before turkey day. I have alot of running around to do tomorrow.
