When i have my car running in park im getting 13.56-13.57 volts on my multimeter but then when i turn on my 6000k hid headlights it drops to 13.13-13.15 so does this mean my alternator is on its way or is my battery not strong enough? Also when i turn my lights on the rpms go up just a lil bit.
My battery has 550cca and its a 88 nissan 200sx 3.0 v6.
