I recently picked up a 98 dodge ram 1500 with about 96k. From the beginning, it has had starting issues/battery dying. so far I have replaced the battery, starter and the alternator. The truck has been running fine the past couple days, but on the way home my check gages light came on and I noticed my battery gauge was way too low. went to park it in my drive way and it wouldn't start again. The battery is currently charging on my porch, but what else can be causing this? I don't know what else to do.
