dual alternators
I see Superduties have dual alternators listed as an option. Anyone have this setup? Do you like it? And how are the loads separated? Thanks.

Electric cabin heater is standard on new Super Duty Diesel's in cold climates. It is simply a supplemental heater to help with cabin warm-up in cold climate since Diesel engines have such a long warm-up time when the vehicle is operated at light load.
In terms of two batteries, that is to provide enough current to crank the Diesel engine in cold climates while at the same time maintaining current for your glow plug system.
Diesels do produce very little heat at idle to start with.
Cold-climate vehicles do come with Webasto heaters as on average commute in cold weather diesel never reaches operating temp.
For some reason Webasto is not an option on US models.
Years ago I ended up in No. Dakota in winter with intention to sleep in the cabin.
The cabin was well warmed up due to hauling, but right after midnight I woke up due to cold. The hot engine at idle cooled down and dash temp gauge went down to 0.
I pushed gas pedal to give it more heat, but it was not much use.
Electric heater not only keeps cabin at comfort level, but also adds load to the engine- keeping it warmer as well.
But dual alternators are installed without electric heaters as well.
Might be good for those who install 4000W stereo in their Superduties.
Hmmmmmmm...I am confused ........You appear to be talking about DIESEL.....
yet you........"Pushed GAS PEDAL".........???????????......:h
My F-350 diesel Dually has 2 alternators....Faster recovery of the Dual Batteries.
Dual Batteries are needed for Starting.....Diesel uses COMPRESSION IGNITION.....VS........Spark Ignition for Gassers.
