Are you having problems with 2004-2008 Ford F250, F350 Instrument Clusters? Cluster goes out , maybe door locks, radio and power windows go out. Gauges don't work. Scanning may indicate a low voltage situation. This is a common problem - a faulty part needs to be changed in Instrument Cluster. They can be repaired here http://www.mrwhizard.com for a lot less than replacement.
