Battery light on

wrong and I had the fuses checked
Unplug the connector from the alternator and spray electrical contact cleaner in the plug. Reconnect and use a volt meter to see what is going to the battery. Make sure the all the connections are clean and tight including the grounds.
My battery and brake light is on just had new alternator put on AutoZone say neef Cadillac convertor

Battery and brake light on means the alternator is bad or about to die. You battery will soon run out of power. Nissan Murano are notorious with failing alternators. Don't buy an alternator from the next autoparts store because you won't get an original nissan alternator but most probably a refurbished or some other brand. You should take your original alternator to an electric shop and have it rebuild. It is cheaper and will last longer.
