I'm driving a 94 Nissan Sentra LE, with 136k miles on it. On my home from work, I drive up a pretty large hill that goes for about .5 mile. During the middle of the climb I noticed my lights were flickering. This includes the headlights and the lights on the dash and radio. Does this sound like an alternator problem? Thanks in advance.
Flicker like that often portends alternator problems or ground connection problems.
You might be lucky and this could be a belt or tensioner issue.
Sounds like bad grounds. Check the wires & connections leading from the alternator & battery negative (to body and to engine block). Remove the ends and clean off the rust/dirt/paint that may be on both the connector & the sheet metal.
