2013 kenworth t660 wiring trouble

Believe it or not if the key is in the on position you will always have 2-4 volts in those turn signal wires whether they are on or not. Without going in to detail just know i learned that the hard way. Most wire testers wont register a signal unless its above 6-7 volts. The snap on wireless voltage tester however will....

 

Did you get this fixed ? I have a 2011 t660 with similar issue

 

did you replace node

 

Having the same issue. Can you plz tell me how or what you did to fix it. Thanks.

 

You figure out what was wrong.

 

I have a2013 t660 won't start with key but will start if relays are crossed

 

I have a 2012 t660 and my rt side works great but left side is real dim...
Then there is a connection for the trailer under the sleeper that I don't know where it goes but when I went to start the truck it started smelling like electric melting...I disconnected the main harness under sleeper and mechanic says there is major feedback thru the wiring...does that control node have anything to do with that...before that everything was fine
