I have a motor with 15xxx on it new battery and alternator. Starter is only a year old. This is the 5th alternator and 3rd battery. I have checked the wiring harness and have found no breaks anywhere. My battery keeps dying every 3 days or so after a full charge. I do have a system in the car but the battery i had before this new one handled it fine never had issues like this. The dash and headlights dim lower higher when accelorating and the heat guage bounces up and down well i drive. But the heat stays the same temp. Something in the car is draining and I can't figure it out. Also I can't seem to find any ground wires on the motor itself. If I'm right there should be one from top of motor to frame. Transmission to wiring harness and one from bottom of motor to firewall. Would not having these wires on there cause any of these problems? Any answers would help.
Why won't my battery stay charged.? on 1998 Hyundai Tiburon

charge and load test battery could be defective...also check your cranking amps on new battery compared to old one

My cranking ammps and cold start are both higher than before. I went with a bigger battery figuring it would give more for what its worth. I'm gonna try the better alt to see what that does.
