Hey I was pulling from a light and my battery voltage went up to 18 (max) and a bunch of lights came on saying servicing soon. Abs needs servicing. Active handling needs servicing. Radio and speedometer wouldn’t work. As soon as I stopped at another light everything returned fine but happened again as I started driving. Just replaced the alternator two days ago so I’m thinking it’s the battery. Any ideas? Also my car wouldn’t shift out of the gear and the power steering stopped working and every time I pressed the brake the abs would lock and pump.
