Hello ILENGINE,
He could have been a tractor tech and not worked on smaller equipment.
Just the same though, I think he would know better than chasing a problem starting at the fuse box other than just checking the fuses to determine what circuit is having the issue.
Former techs don't think service information is important until they don't have it available any longer. Some even ignore it when it readily available.
Old tech mentality: I don't need to read nothing.
Guess who is to blame for the newer tech's bad habits and ignorance?
