Never seen one of those before. Looks like a switch that disables the wipers when the front window is stowed. Is that how it actually works?

Correct, saves you from getting slapped in the face by the wiper.

whered you get that diagram. ive use site http://www.catsch.info/renr3539.html but i cant download in pdf
really want to use ipad, printouts have been ****
For printing or posting small sections like this I use Windows own snipping tool, for complete schematica I just do it directly from Cat SIS.

G..G..G..Granville.........!! Fetch your cloth.
Are you still looking for a complete electrical schematic.? I can send you one.
One thing I would say is that IMO an iPad screen is too small on which to read a schematic. I have a 20" screen on my laptop and at times even that isn't big enough. It can be worth your while getting hold of the schematic in pdf and having a local print shop produce a paper version on something like A0 (46" x 33") size paper.

What information are you chasing? If it's just the interlock switch the p/n is circled in the image above.

i just find it posted to website each time i need, but there are ads everywhere and ive tried 10 ways to save as pdf and it comes out all wrong. have each section screen captured but thats a pain tracing

chrisso, its my machine. planning on using it a lot and just my first time tearing it down this far. adding a pile of lights and sensors. have other posts around here getting it up and running to make some money.
