The rotten egg smell usually occurs from time to time. It comes from the battery being charged by the alternator. However, if it smells continuously there is a problem. It's likely that your alternator is overcharging the battery. This needs to be looked at soon. The alternator will need to be replaced or repaired. Hope this helps.

Alternator burns out
You have a faulty battery, that's probably what killed the other alternator. The rotten egg smell is gases coming from your battery. Change the battery before you cook the second alternator.
