i just got a 90 civc and the battery light comes on when its runnin and it will have the lights dim out and stall right out after a while its bone stock but my friend said wen it stalls it has black smoke come out then cut right off but it also smokes wen ur on it a little bit it will smoke blue smoke get back to me

if your battery light is on with the car running that the first sign of a bad alternator. might get it tested. if your voltage drops too low that will cause your car to stall (fuel injection wont work without battery voltage)
