Battery Drain

[WiccanQ45]

I have a 94 infinity and i recentaly got a new battery and it has been running great. But i went to go start it and the battery was very dead, i can't figure out the reason behind it being dead eitherl. Both the head lights and the inside lights were off. Is there any thing besides the lights that i should be checking for that would drain a battery so fast.

Your alternator could have a bad diode therefor your battery won't get charged. I had that happen to me, the alternator acted fine but didn't charge the battery due to the burned out diode.
