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...

My friend is a Honda Vehicle Technican who owns a 1994 Nissan Sentra which had kept dying on him. He had called the AAA driver who stated that the alternator was good as noted on the print out report when the AAA driver ran the check on the system. It turned the alternator was bad, which somehow also affected the starter. While the AAA driver had jump started the car, the ignition switch relay got broken; and the small positive cable connection got a short; so it all, he replaced the alternator, the starter, the battery and got a new battery cable connectors, ignition switch relay and fuse for the inside of the interior lights -- and he has no problems since after spending 4 days on this problem. It would had been easier had he had a lift and the right equipment but nevertheless he got it done but missed his work -- but at least its fixed.

SOURCE: 2002 Nissan Sentra car will not start but battery is 100% charged, will start when boosted though

check your battery cables to see if the cables themselves are corroded and also check the connections where they connect to the vehicle that they are clean
positivecable will connect at the starter and the negative will connect to the engine some where.
if this does not help then have your starter tested to see if it is dragging. as it could be the armature or the brushes in the starter.

SOURCE: nissan serena alternator

You must test first if your alternator produces output voltage (usually about 13.5V)
A test light is a simple but extrememly useful tool.
If you are trying to diagnose and troubleshoot an electrical problem, sometimes a test light can help you rule out possible causes much more quickly and easily than a DMM (Digital Multi Meter)

Using a short socket of appropriate metric value, and a pry bar; Push the pry bar toward the firewall to loosen the tension on the belt. It's not that hard once you buck the initial spiral spring pressure of the tensionor. I have even pryed against the tensionor with a blunt heavy bar and moved it enough to free a belt.

94 Nissan sentra will not charge battery but wit car off battery reads 12 Volts then when u fire it up the volts drop down to 11.76 can't find any thing to solve this what s the problem

First, check the belt that runs the alternaotor, make sure it is'nt slipping...

Then have the alternator checked out, this is probably your culprit; as the alternator slowly wears out, it will still send current, but not at the peak performance. if the alternator checks out fine, inspect wiring harness to make sure all connections are good.

1985 nissan sentra new alternator and battery wont hold charge fan on toggle switch having electrical issues

that may be the problem, if the relay is activated it will drain the battery, try removing the fuses for the cooling fan to see if this is the problem, start with that, remove power to fans, even remove the fan relay or relays,

Troubleshooting alternater for 1997 nissan sentra - alternator is good and battery is good also ,but it still will not keep the battery charged while running

Check the wiring between the alternator and the battery, especially at the battery end there is a fusable link there that might be blown.
