Look like you got a bad alternator

Possibly a bad fuse which is not allowing the power from your new alternator to make it back to the battery. Do you have alternator voltage making it to the battery when running?

Mary;You Got it Rite-The original problem was a signal of failing alternator & it Sounds like the rebuilt is dumping already(Not Highly Unusual)

did you remember the 10mm nut and battery cable connection? also the regulator plug connections to the alternator unit? check also small fuse box under hood near battery tray, for 7.5amp fuse labeld alt-s is the fan belt tight?

My wife and I have owned three 1994 Sentra cars. One of them went through batteries and alternators like crazy. Last time the 1-year old battery died, I replaced it and went straight to an auto electric shop. The technician found the alternator was putting out about 77 amps the entire time the engine was running (factory alternators are rated for 80 amps, but only when charging nearly-dead batteries). He also found that the harness running to the alternator was hot enough to scald you if you touched it. Miraculously, I found a factory NOS harness on eBay and bought it. Easy to put in, and the car went from a maximum charging voltage of about 13.1 volts, to a MCV of up to 14.1! Haven't replaced a battery or alternator on it since. Hope this helps someone...

you need an alternator. it failed. have your alternator checked. im pretty sure (99.999999%) that it failed.

Your problem is pointing to the alternator. Since you say the alternator is only a year old, the I would check the tension on the belt (deflection should be about 1/2 an inch), and the belt itself. Your problem most likely lies in either the belt, belt tensioner (if applicable), or alternator.

Your alternator is dead/dying. Nissan puts both of those lights on to tell you that the alternator isn't charging your battery.

check out put alternator if it out put too much computer will shut off to keep from doing further damage to electrical system.
