i have a 1991 nissan nx with a sr20DE motor, i drove 800km until my alternator seized up and broke the belt and harmonic balancer, i have a new battery, new alternator, belts and the harmonic balancer was repaired (welded) but there are still two lights on in the dash, the battery and the brake one. any ideas?? i need it fixxed ASAP so any input would be great! i was told to check all the fuses and relays but they are all fine and was told to check the voltage regulator ( is it internal or is there one in the body of the car??) thanks heaps.
