Had this occur a few weeks ago on a 8560. Check the 5 amp fuses in the fuse box. If they are good but do not have any power on either side the relay for the fip solenoid could be bad.
Thanks, you pointed me in the right direction. I took the 5amp fuses out and no voltage. I noticed the relays below the fuse box and took them all out. One was marked horn and one shutoff. I swapped those two out and she fired right up. Thanks!!!
