579 Headlight Trouble

Check fuses?

 

25Amp fuse labeled L2 in the engine side fuse box powers the left high beam and right low beam.

 

What fuse powers left lowbeam.

 

J2 is LH low RH hi

 

i have this exact issue with a 2018 579 and ive been chasing it for a while. have changed the bulbs, fuses, wiring harness, multifunction switch that controls the high beams... ive take the lights off the tractor altogether and wired them up outside of the truck using power probe to manually light them to no avail... this truck is driving me crazy... did the fuse fix your issue or was it something else?

 

I am having this exact issue with a 2018 579. I have changed bulbs, fuses, wiring harness, multifunction switch that controls the high beams. I have taken the lights completely off the truck and powered them manually with my power probe and I have come up with nothing to explain why this is happening. What was the ultimate fix for this issue?

 

I apologize... the Pete I'm working on is a 567... not a 579... though I don't imagine the issue differs much.

 

Did you figure out what the problem was? Im having the exact same issue.

 

Just to follow up. I have a Pete 567 2018. I had the right high and left low beam out. I started with the bulbs, then went to fuses, then checked wires out under the hood for chafing. Checked harnesses.Found no issues at all. This went on for 3 days off and on between loads. Finally gave up and took it to the dealer. They ended up finding a chafed wire just outside the rats nest of wires coming from the chassis node under the driver seat. ( I looked there several times myself but concluded that there was no way wires could rub because they were zip tied so tight) The dealer had it for 3 days, but the bill was only $324. Not too bad all told, but still kinda pissed I couldnt find it.
