all, I hate to beat a dead horse but I am really getting to a lose. Friend asked me to fix their car. They had a bad alternator that killed the battery, both replaced and car worked. then power steering failed. read the forums and found it is common. got a pump from the wreckers, car worked for a few days, then when you turned the car on the battery light was on unless you rev'd the car about 2k rpm, now the light stays on... it is charging at 13.8V, grounds all check out good. disconnected the power steering pump and fan and light still on.
Ok, so the alternator output is 13.8v? is that under load? Have you tried adding voltage (ie jump box, or full field the alternator)? Does it have a sunroof? I know that last one is a strange question, but it could matter.
ya, I put all lights on etc, wipers load it up and it always idles fine and charges properly. if the light is on with the power streering disconnected am I safe it say it is ok? it only has 30 days warranty and dont want to risk that.
if it charges to 13.8, that should be good, but the DME should recognize that and turn the charge light off. Thats the big concern, do you have some excessive corrosion somewhere? Have you checked and cleaned all connections for charging points and grounds? Thats where I would start.....
