loosen adjuster bolts and take off belt......
This vehicle (like most cars) has both a starter and an alternator. The alternator is driven by a serpentine belt, and the starter is located on the lower part of the engine at the transmission, where the teeth engage with the flywheel/flex plate. An alternator for the 1992 Sentra usually costs around $120-150, and a starter in the range of $90-120.
Your alternator is defective. Could be the internal voltage regulator or one or more bad diodes. Replace as soon as you can to avoid getting stranded on the road.
bring it to transmission shop
are they the same size? did the car the alternator come off have the same options or more than the one your going to put it on as the amps could be less and you have a/c on your car and head lights on same time could cause problems you don't want

Behind the water pump
The flasher unit on a 1992 Nissan Sentra is located under the dash, near the hood release. It sends an intermittent signal to the turn lamps to trigger the familiar flashing.
The 1992 Nissan modulator valve can be found on the firewall in the engine compartment. The valve will be on the drivers side of the firewall.
Disconnect the battery, loosen tensoiner, " the top middle wheel, under distributor cap" disconnect the wires on the alternator , unbolt and good to go
