666 International Lights

Rusty King · Feb 23, 2010

I just bought a 666 and am having trouble with the lights. I bought a new switch and still having troubles. I bought a IT manual and it doesn't have wiring schmatics in it. Does anyone know how to get ahold of these?

Yeh i just got done doing lights on a 656 and a 686 and they are a pain you need a lot of patients lol. Ok i found the fuse holder was bad and if you take the wires of the light switch they are coroded .If you can get a hold of a 656 operators manual there is a good wiring diagram in there. Or go to your caseih dealer and get a printout of the wiring. You can get a bit of that if you go to caseih.com but its not to clear. Erik..

I have the factory service manual for the 666. It has all the wiring schematics in it. If you can't find one online or from your dealer drop me an email and I can scan and email them to you tomorrow.

If you could email me a copy that would be great. Mine has the "86" series switch with all the wires in one plug if that makes a difference. Thanks! My email is [email protected]

My manual doesn't cover the 86 series but the wiring should be the same as far as color coding goes. Is your 666 a row crop and what engine does it have, gas or diesel? There are different schematics for for each tractor.

Mine is a row crop with a gas engine.
