i have a 1990 civic si with a jdm 1st gen b16a in it....it's been working fine for the past 2 months but yesterday, when i was coming back home, my car just didn't turn on. at first, the alternator, oil, seatbelt, etc. lights came on but as soon as i cranked my motor to start up, the lights went dead. after that, i couldn't turn on any of my electrical things (lights, radio, clock). i checked some of my fuses, and none were broken. i jumped started my car and drove it home ok. then i woke up this morning to drive to school, and same thing happened. as soon as i crank my car, the alternator/oil/seatbelt lights flash on and then die immediately. does anyone know what this is? i hope i don't have a short in my car somewhere, i wouldn't even know how to find it...
