Confused..need help decide
Ok guys/gals I have an issue but based on reading thru the archive I feel undecided to what to do...I have possibly an alternator or regulator problem...situation first started Friday night when I recieved the warning lights
1. battery/alternator work shop
2. undervoltage consumer defective
Basically thru reading thru archive the valeo regulator is not replaceable but I've been told by MB tech yes and there are part numbers for it. I decided try the Advance auto refman alternator but had two issues
1. the socket to connect it to battery is a couple of mm to short so won't lock into place
2. we found out after trying to install it that the pulley up front of alternator didn't move at all(so returned and waiting on a replacement due tomorrow)
Funny cause even though my original alternator pulley turned freely we checked again like an hour later and it wouldn't turn either...hummm
Anyways what are the common symptoms that show its the alternator is bad or the regulator is bad?
please help.
Incase it help I will add this
next day I took car out to buy breakfast and after about a half hour things like the radio and other car devices stop turning on..as I waited with no load on car and eating my breakfast in a nearby parkinglot the car on it was low idleing after a while then I decided to try to drive her home but the trans wouldn't come out of park so I turned it off only to find out car won't start..I got a jump drove it to a shop and they charged my battery for an hour and I drove it home and its in my garage.

you should be able to take the alternator to autozone /advance oreilly's whatever you have in your area and have it load tested to see if it passes or fails
check you battery at the same time

03 g35 coupe...........02 c32 Sold
i believe the mb tech thinks the regulator can be replaced because the c55 and all the 05+ class mercedes used a different alternator in which the voltage regular can be replaced.
I know the c55 and 05+ have been confirmed to have a replacable voltage regulator. Scottw911 stated that the c32 wasn't replaceable. Since he seemed like a knowledgeable person, i took his word for it since i couldnt afford the down time.
There was no warning sign. When my alternator went, it went. I think it was the chip like others have said since the pulley would still spin. The stock battery can give you about 45min of power without the alternator. I suggest replacing the alternator asap.
