Hello and thanks for your question. My name is XXXXX XXXXX X will do all I can to help.
Let me first ask, do you know what your voltage is at the battery while engine running? should be around 14.
No I don't
after the garage told me they are unable to get rid of the message and warning lights I went to Advance Autoparts and had both battery and alternator checked out and they both work fine according to the print out
OK, The problem is the voltage regulator.
The alternator itself is fine, and most likely charging fine.
However, the voltage regulator when it acts up, sends a false signal to the instrument cluster.
Where is the voltage regulator located and is that a part that can be replacedIs the voltage regulatlor part of the alternator
It's pretty common. You get a "Charging System Service" message.
It says " urgent power system failure"
Volvo does not offer it seperate.
So you are telling me that it's part of the alternator and the light will not go away until I get another alternator, or can I take it out of the old one and install it in the re-built one?
That is correct. The warning light will remain until another voltage regulator is installed.
It is charging, it's just the instrument cluster doesn't think it is.
One last question can I take the voltage regulator from the old one and put it in the re-built one?
Is there a way to interupt the message without having to install a new voltage regulator
Yes you can. and it should work fine then. How long ago did you replace the alternator with a rebuilt one? has it got a warranty? maybe get it covered. We've had mixed results with these aftermarket rebuilt alternators. Bout 25% of the time when using one, it will charge, but you get the message on the instrument cluster your having.
"Is there a way to interupt the message without having to install a new voltage regulator"
not that I know of. The electronics are pretty sensitive, and if the instrument cluster doesn't get the correct signal. It will throw the message.
Ok thank you for your helpl
absolutely. thank you.
Let me know if you have anymore questions.
Had it rep;laced on MOndayd
Should have at least a year warranty on it then.
Is the voltage regulaltor that small little plastic part with the soft jelly in it when you open it up
Number 3 in this picture.

Sorry I got it thank you Eddie I am pleased with your answer
