ok i checked all connections and they all seemed to be tight. there is a bit of black grease on the clamps though. i also drove thr car on the highway at about 2500 rpm for an hour without any accessories on. i have lots of accessories including an aftermarket 600w amplifier. then when i got home i took readings and it read 12.7v car off and 14.3v on. so i think my battery was just low on charge. now my only concern is discharge rate. i will be checking the voltage again tuesday to see if it can hold up in ~30'f temprature.
