Installed a new battery and started the car. Voltmeter gauge reads around 13 volts. Cool. Turn the headlights on, gauge reads about 12. Cool. Hit the brake pedal gauge now drops below 11. Not cool.
The owners manual says the gauge should stay between 12 and 14 with loads applied. Mine is dropping below 11. Any ideas? Bad Ground? |
