2003 P42 Workhorse Step Van - Batteries charged, no lights/won't start

[LoriLynn's]

Hi there,

I'm new to this forum (and to diesel trucks). I have a 2003 P42 Workhorse Step Van. It was running great until I went to start today. No lights, electrical work at all. Both batteries have 12.8 volts on them. Don't know where to go from here. Is there an external main fuse? We can only see the internal fuse box and owner's manual doesn't show an external.

Any ideas??

Thanks,

Lori

Did you ever get this fixed? Are there any other problems like maybe the ignition switch?

Thank you for checking. I did get it fixed. We loosened and then reconnected the contacts on both batteries and the one to the main engine block and it started right up. Phew!
