Put Battery In Backwards Car Wont Start. He recently tried to install a new battery. Headlights and door chim work but nothing else.
First you wont make it that far. It doesnt matter how many volts are stored in your cars battery if it doesnt have a strong ground connection you wont be able to start 2 Low Voltage Car Battery. Instead of connecting the positive cable to the positive battery terminal and the negative - cable to the negative battery terminal you hooked them up backward.
My Lexus 2002 es300 wont start after changing the battery.
The direction of current flows matters a lot in devices having diodes. Similar symptoms will be experienced when you try to jump-start a dead battery but accidentally connect the jumper cables backward. Even if you dont realize what you have done your car will not start because of the wrong connection in your battery. It wouldnt start after the battery was out in and an experienced mechanic came to check it and diagnosed the problem.
