battery is fully charged, alternater shows voltage and holds charge, battery however will not stay charged after a while at fully charged it will eventually die and then can be boosted but after removal of cables dies again. replaced engine before problem started don't know if everything was hooked back up any ideas
Engine off the battery terminal voltage should be about 12v, engine, about
14v.If there's no voltage change, then the alternator current is not getting to the battery. Look at the big fusable links on the battery + terminal and in the junction box.
If it is charging, then there's a drain somewhere. Do you have an aftermarket stereo? These often get misconnected. Perhaps its not switching off. Start taking out accessory fuses until you don't get a current drain.
