Hi Richard,
The problem is with the initial extent that you have specified.
If you see the mapservice for TIP Points
http://data.cmap.illinois.gov/ArcGIS/rest/services/Maps/TIP/MapServer/0
XMin: 883495.453957755
YMin: 1665586.62128334
XMax: 1203770.39280292
YMax: 2122601.04780384
Spatial Reference: 3435
Your initial extent in the code was
xmin="-89.84"
[LEFT]ymin="40.65"xmax="-86.34"
ymax="42.97"
This caused your map to be zoomed in so close that you did not see anything.[/LEFT]
Change the initial extent to the max extent of your mapservices and you will see the base map. Find also works.

I looked up "01-97-0085" and it did return the results.
