Anyone know where I can get a new holland 6635 cab 4wd schematic?? Without paying 450 bucks? Got one in with loads of problems.. no dash lights, flashers, headlights, rearend lock and 4wd not changing/wkg?? fuses and relays appear to be good at the fuse box...

is there a main relay??

and the wire going to the grammer seat.. is it a safety?

Thanks for any help.. sotxbill
 
You should be able to buy the electrical section alone for a hundred or less. If there's 2 wires going to the seat, there is an operator's presence
switch. If there's 4 wires it has an air suspension seat too.
 

Thanks Rick.. its two wires on the seat... and when I connect them with a jumper, the turn signal fuse pops... assuming the fuse cover pictures are correct.. Tractor starts irregardless of anything. And a bypass wire is run to the injector pump from the ig switch..... but no dash, no 4wd, no locking, no flashers, no headlights.. all fuses are good now and all big relays are replaced. It will really need a schematic for me to go forwards... I suspect the initial circuit that feeds all the other relays is not working??? if that guess makes sense... wipers work, cab fan do work off the ig switch.. I see what I can order..

The fuse/relay diagram is only an approximation of the actual circuit paths. Look for pinched or shorted wires in the seat switch circuit. There
may be a maxi fuse or two protecting major circuits ahead of the fuse box.
