Having problems with your Cars & Trucks ?
I got a merc 2002 c200 kompresser. And on the malfunction it shows BATTERY/ALTERNATOR
How should i know if its the battery or thr alternator..?
But a multi-meter on the battery with the car running it should be around 13.7 volts, if its lower then its the alternator
