Hi Sue,
There is a fuse box near the brake fluid container on my 2004 V-10. The "house" solenoid is fused at 60 amps inside that box. There are also relays there for the 7 pin trailer connector. There are other relays as well. I would do a continuity test on all the fuses.
There are another set of fuses under the dash on the drivers side. Very nicely put where you can't see and there is little room to work. Check them all.
There are at least two solenoids--on my 2004, one for the starter is in by the passengers side headlight area. Another is down below the battery--that is the one for the house batteries.
You can try jumpering across each solenoid, but be careful.
