lights flickering

[btomike]

my 1992 truck is scaring me. my lights flicker when turned on. plus with the lights on or off the voltage gauge is under 14 and mover down and up. this is what i find strange though, when i was driving up to college at highway speed, the voltage gauge never got to 14, where it usually is. does anyone have any ideas what it could be. my brother checked the altenater and said it was good, could it be the batteries? :confused:

I it could very well be the battery but being as you voltage never got to 14 volts i would still suspect the voltage regulator in the alternator is shot. Best thing to do is take it to a parts store and have them do a load test on the charging system that will tell you what you problem is.
