In the 1988 Nissan the alternator, instrument panel, and backup lights shared a fuse. Before changing a fuse see if the backup lights work (have someone watch when you are in reverse). If the neutral start/backup light switch is broken internally, it can be blowing the fuse when you put the car in reverse.
could be a bad alternator or battery
this happened with my 94 sentra just before the alternator died... i would take it to a parts store and have them test the battery and alternator.
check the alternator
When the alternator goes bad or goes out completely, the car's battery will be drained. I suggest you pull the alternator and have it tested. If the alternator is bad, you will most likely need a new battery as well. The cost is around $200.00.
To remove the alternator on a 1994 Nissan Sentra, first disconnect the negative battery cable to avoid any electrical shorts. Then, remove the drive belt by loosening the tensioner, and take note of the belt routing for reinstallation. Unbolt the alternator from its mounting bracket and disconnect the electrical connectors. Finally, carefully lift the alternator out of the engine bay.
