On vacation and need some advice...
Started my 04 yesterday while at the beach on vacation. Immediately accelerated rather quickly out of a parking spot onto the street and the battery light came on for about 10 seconds. OBD reader still showed 13.7 volts. Started it and drove twice since then. 13.6-14.1 volts. Battery is 2 months old. New starter as well. 4 hour drive down to the beach voltage was 13.5-14. Fluke? Maybe slipped the belt for a second? I'll keep and eye on it, but if OBD is reading 13.4 or better, alternator is working fine, correct? Also, if it goes out and battery is new and fully charged, approx. how far can I travel without the AC, radio, and lights on? Just causing me some stress while on vacation. Might overnight a new alternator in case. I have tools and can swap in under 30 minutes. I guess my main question is if the OBD reader shows good voltage, then it's charging fine? Thanks in advance.

I just went through the battery warning light/dead alternator situation. I took my alternator to 3 different parts stores in town, and not one was able to correctly put a load and test the bosch alternator, they didn't have the correct wiring. So I took my regulator/brushes out, and the brushes were at the end of their life and bit burnt, I was able to clean them up and run the alt for a couple weeks until I found a replacement regulator online for 25 bucks, rather then spend 300 on a new alternator. So you may want to take out the alt when you get home and look at the brushes, very easy job, they are located under the plastic cover on the alt.

So, made it home ok. No voltages below 13.4 the whole week, mostly 13.6-14. Pulled in the driveway and wanted to test the alternator. At idle in 94 degree temps I had on the AC, full blower motor, radio, front and rear defroster, and high beams. Voltage dropped to 12.8 on my obd reader. Back up to 13.4 with just AC, blower, and radio. Sound normal?
