Hi,
What causes an alternator to fail to excite/generate?
At the first start after sitting for a long time, my battery/alternator light will stay on along with my abs light. The engine will run and I'll get 11.8-12.2v. As soon as I give a tiny bit of throttle, both lights go out, dc bus voltage is 13.6-14.1 (I have a 14.1v regulated alt), and turn on/off doesn't create any issue - until next cold soaked start.
Belts are within a year and tight, connections are clean and sound.
Thanks!
