My altentor and e-brake dash lights are on, and when i’m driving they both start to flikker at the same frequency around 3000rpm, along with that bug zapping sound. i just checked voltage output at the battery and it’s a steady 13.8V’s, with full load. Also the when the dash lights flikkering so does the daytime fog lights. ---

yah i changed the altenator and all the electrical issues went away. I guess that all it took was 200mV to fuck the car up.
