Gauge Question

Just finished doing the MAD change over on my 65 Dart. Now I have a problem with the fuel and temp. gauge not working. Dash lights are working and engine starts. Checked both sides of the fuse with test light and light does not come on. Dropped fuse block down and rechecked feed wire for instruments and test light does not come on. All other connections on fuse block are hot. Would like some suggestions/help as to what to do now.
