70 AMP Alternator for 1988 300E
Problem: Battery Died
Bubba diags: I charged the battery and started the car. I disconnected the negative battery terminal and the car stopped running.
Conclusion: Charging system is bad.
Question: How do you check if the alternator or Voltage Regulator is the charging problem?
Note: Obviously the regulator is a more cost effective fix, so I want to be able to check for that first.
Any help is greatly appreciated.
