Hey guys something killed my new battery and made a dead cell in it. Now i just dropped an engine and im trying to work out all the kinks with the car. Car was running fine but i did not have any brake lights and my temp gauge did not work. So i looked at my brake switch and the wires were cut at the connector. So i went to junk yard retrieved a new connector and and connected the wires the result now my brake lights work. Next change was my temp sensors, my sensor on the cylinder head was broken and not connected so i replaced it and also the sensor on the water pump. Temp gauge still doesnt work. Now since i did these things something is killing my battery any ideas?
