2003 Hyundai Sonata Q&A

2003 Hyundai Sonata Question: the battery is good and the alt is also good battery is not charging

old alt was at 8v with engine running, i replaced the alt -
Answer 1
check for power going to the alt if you have power you might have a defective alt -
Answer 2
Which post (wire) is reading 8V when running? Normally you should see battery voltage while running , if alt is not charging, 8V would tell me either bad cells in battery , or excessive corrosion in wiring/connection(s). Get circuit info so you know what to expect. Fully SLOW charge the battery and then test , before putting on more parts. -
