See it's such a pain to get to the alternator, so I had a mechanic do it. What should I tell him to check?

 

bad ground/open neutral maybe...

also...I noticed with mine during winter, if i have my headlights, heater, heated seats, heated mirrors, and my radio all on, my battery guage sits at 13.5V. Then i hear my SAI kick on and i see it drop down to almost 12V...sometimes makes me think that a bad SAI could cause a bad short when its activated and could drain the battery while the car is idling.

 

Man how am I the only person with this problem.. amazing

 

New update, revved engine today and the volts shot up to 14, and for some ******* reason the battery light turned on... go figure
