What happens when your car battery is high?
Voltage will become dangerously high. The battery can overcharge which will leave it useless. Engine components that aren’t designed to handle the pressure, temperature or power will be damaged. The alternator isn’t designed to handle excessive power and eventually it will burn out.
What to do when your battery light comes on while driving?
If the battery light comes on while the engine is running and the vehicle is being driven, this indicates a problem with the charging system. Step 1: Turn off everything that draws power.

To see what is really wrong with the car see this video for things you can check.
What should voltage be for car battery light?
It’s relatively easy to check the function of the alternator with a multimeter. The voltage should be between 13.6 volts and 14.6 volts. If the voltage is less than 12 volts, the battery light is triggered and you’ll likely need to replace the alternator.

How to test battery light at high speed?
When you test with your voltmeter you need to crank up the rpm’s to the same rate as when you are cruising along at 70mph. If your car has a tach in the dashboard, rev it up from an idle to rpm you see at 70 mph. Listen to how the motor sounds. Then do the same when you have the voltmeter attached and check the output voltage at the high rpm.
