New battery in my 1999 Ford F350 Fleetwood Class C. Motor started instantly. Cranked a bit on the generator and then I stopped when it didn't start right away. Generator starter refused the second try. Now, neither motor nor generator will crank. Seems like there's power to everything BUT the starting motors. Checked batter connections and they're fine. DNK where to go next since BOTH the generator and the motor starters don't turn...
Thanks

 

Are the headlights shining brightly? No? Check the integrity of the battery cables, should be tight and corrosion free at both battery and termination. Corrosion within the cable (usually near the ends) can lower a cable's capacity to carry current. You last start may have heated damaged section enough to open the connection.

 

Try to start it while the interior light is on and see if it dims. That will tell you if you have a bad connection. You may have blown a fuse. Check the big fuses in the box under the hood.
