It is definitely two alternators. There is a sticker under the hood from Ford for routing of the two serpentine belts for the dual alternator setup.
I talked with https://donbrownbusparts.com/
they were super helpful. I gave them the serial number of the condenser and they told me lots of info and got me parts at a good price.
I had to grind the bolts off the old condenser to remove it. The salt from New York is crazy destructive. I live in TN but the bus came from NY. I will be spending a lot of time descaling and painting the underside. It took a couple hours to just do the area where the skirt condenser goes.
Does anybody know of a good resource for refilling the system with freon and oil? The bus sales and service place near me says they are booked until next year. I have a feeling a regular car place won't do it correctly.
