Battery possibly not charging
Hey all, I may have an issue with my battery not charging. I replaced the voltage regulator cause all my lights, interior and exterior, kept flickering constantly, kind of like strobbing. After I replaced it, the flickering stopped which is good but I checked the battery voltage while idling and it was only at around 12.3 volts, 12.09 with the A/C on. Drove it about twenty minutes, probably a few miles and then rechecked the voltage and it was still the same. Not sure if this is normal, I know it should be higher. This is the voltage regulator I bought...

My vehicle has the electric rear defroster though, so maybe I purchased the wrong one? Any advice would be greatly appreciated.

I think the flickering is most likely due to a bad alternator, worn out brushes or a bad diode the most likely culprits.
Your defroster option should not affect which battery you should have, the demands of the starter motor determine this. The size of the alternator you require IS determined by the demands of the cars electrical system, ignition, fuel pump, stereo, defroster, lights etc.
You should have a reading of 13-14.5 volts across your battery terminals of the charging system is ok, even with lights, heater fan and the stereo working.

Ok all, update on my issues. Replaced the alternator with a 63 amp alt. And exchanged the voltage regulator I just bought with a mechanical one that also is 63 amps. After installing these I checked the battery and it was way way overcharging, it was something like 17.6 volts. I believe I might need to adjust the voltage regulator, but I am not familiar with how to do this, any advice?

Ok, replaced this voltage regulator with a 63 amp solid state one I stumbled upon. Installed it and voila! No more flickering lights, battery is charging right around 13.8-13.9, all is well. Thanks everyone for your comments.
