    check the votage on your battery while it is running. should be around 14 volts......then fire up all the lights, ac fans and radio, exc... if the volts drop below 12 or 12.5 you are draining......

    stupid lights????? MAYBEE GET SOME DUCK TAPE TO COVER UP THE LIGHT ON THE CLUSTER :p

    THE DISCONECTED BATTERY WILL RESET YOUR ECU.

    you might have a dead cell in the battery.... take it to an automotive store and have it tested. If its bad, your B light will come on, but the battery will still HOLD a charge, and be able to start the car. Although while the car is running it may bot be strong enough to power accesories within the car.

    i have a short on my car i cant find. you may have the same.

    test
    1. disconect ground from battery

    2. connect a volt meter to the ground from battery and to the ground from frame.

    if your volt meter desplays a reading you have a short

    Its not the battery because ive used a different one and it did the same. The shop that rebuilt the alt said that disconnecting the neg while the car is running is a bad idea. Im thinking its probably a short somewhere too. Another question for everyone is im using the original injectors that came with my b16a and I was told they are a different ohm and I should get some crx si injectors. Is this bs or has anyone had a problem with em?
