2002 2.6 Elite. On the way home, car running fine when the battery warning light comes on, still running fine. After a while the display begins to dim and the ABS / TC lights come on, I continue to drive but turn everything electrical off, instruments stop working the engine and steering start to feel sluggish, other lights come on including the engine management light. I got home turned the engine off, tried to start it - nothing. Voltage at the battery reads 9.8v. After a couple of hours on charge the battery shows 12.3v, engine starts and all the lights are out apart from the battery light. Checked voltage at battery with the engine running - 9.8v
Alternator goosed? If it is what is the best advice for replacement?
