Been having some trouble with my charging system, completely out of the blue.
My battery, alternator and starter are less than a year old. Duralast battery, remanufactured bosch starter and alternator.
With car jump started and idling, nothing on, I get ~12.2 across the battery terminals, clearly not enough. This is why my car was not starting, even after long drives after getting jump started. Engine speed does not change the output. Car will run alright after getting jump started as long as I don't put on too many accessories. If I do (say, rear defrost, blower 3, radar, radio, and high beams) too soon after getting jumped the antil-lock light on the dash will start turning on and off regularly as I begin to lose power (radio is the first to shut down/restart). This happened a mile from my house as I was driving and I was afraid the car was going to die while in motion it was so severe.
Engine ground, alt ground, and all other wires are all tight and solid. Battery terminals tight. No trouble starting as long as I get a jump or pop start. A little more deflection in the alternator belt than I'd like, but I can't turn the alternator fan by hand and it's by no means loose. Alternator has about 1/4"-1/2" of front to back movement. Related?
Why is my <1yr old starter only putting out 12.2v? Why is my anti-lock light turning on and off in relation to my car's electrical health? Should I simply request an RMA on my alternator and call it a day?
