97 F350 question; I just bought this truck and loving it; my first diesel.
Question: where can I read about the battery setup? I’ve searched and not found much. Are they tied together or does each power unique circuits?
On a separate note, what is the best manual for this truck? Back in the day, Haines published good manuals...
Batteries are tied together. If one is going bad it will pull the other down, change in pairs. Lots of good info in the stickies at the top of the page. Welcome!
When I am back on a PC, I will link you to the factory manual.
I like Haynes and Chilton for odd tips on systems you will be fixing that the factory manual omits or expects one to already know. Armed with all three you should be able to fix everything.
Spend the cash on better batteries. They have a higher CCA and could be difference between stranded and starting. Group 65 is what you need from memory.
