The battery pack suddenly becomes negative voltage

An unbalanced pack or a pack with a cell which has a low capacity will correctly result in state-of-charge drift. In these cases, the BMS is working correctly since the battery pack has a reduced usable capacity. To resolve this, either the pack must be balanced (if out of balance), or the weak cell must be replaced (if caused by a weak cell ...

Ignition Coil Basics

The coil becomes a transformer, stepping the voltage up. If your car uses a 12 volt battery, the 12 volts you put into the primary side of the coil will exit the secondary side as 30,000 volts! The high voltage is carried away from the coil by a high-tension cable that looks like a short piece of spark plug cable and runs to the distributor tower.
