1992 Accord with a F22A6 motor.

Battery/Charging light started to intermittently blink on me a week or so ago so I replaced the alternator with one from NAPA. All seemed well until it started doing it again. I went ahead and got a new free battery from O'reily's just to make sure that wasn't the issue. Again, the light will still randomly blink while driving. Had the battery and alternator tested by O'reily's and they're both good. Battery puts out a little over 14v at idle and the alternator is pushing 45-50amps with good diodes. I also pulled out the multimeter and did a drain test and couldn't notice anything abnormal. Also, the battery light no longer lights up when I turn the key to the ON position. Something is definitely screwed up but I just can't figure it out.

Nothing besides the radio turning off has happened yet, but I have a feeling that it's only a matter of time before I'm left stranded with a messed up electrical system. Any help would be greatly appreciated.

 

Did you check the positive and negative wires going to battery. Make sure the metal tabs are not corroded. You have to disconnect the battery, (Make sure you have your radio code because it will reset your radio, if aftermarket is installed then don't worry). Unscrew the connector from the wire and check that metal tab. Make sure it's not rusted to hell. Had similar issue on my moms mini van last night and that was the problem. Car lights work, but it would turn on sporatically. You may need to replace battery wires (Positive and Negative at the same time while you are at it)
