I own a '79 240D, and need to find an alternator that can handle an electric in line fuel heater. The heater that I will be using, draws as much as 40 amps when first turned on, then regulates itself as the fuel temp gets warmer.
Are there any later model Mercedes' with alternators that could handle that load. I was told that these heaters have been wearing out the stock alternators on these cars. Thanks for your help.
