2590 lights - no low beam

Dave F · Oct 20, 2014

Low beam doesn't work when I switch the flashers on for road use.

High beam works as it should, just no voltage on the low beam circuit at the lamps. Is there a relay or breaker somewhere or should I start looking for a broken wire somewhere?

Good news is it's only a problem at night...

Thanks

Right under the step there is a plastic connector with a ton of
wires, my guess is your problem is there. Look on the CNH
parts site and get the wiring diagram and poke with a test light
to see if you are getting juice through it to the wire. I assume
you ou have already checked the fuse?

I would agree that the most probable cause is the plastic connector under the cab. You need a small socket to remove it. There's probably some corrosion in the pins there. Clean them up with a piece of emory cloth and electrical contact cleaner.

There is also a connection near the front of the tractor behind the right side panel. Check to make sure that connection is tight. I would also check at the fuse panel to be sure you are getting a good connection there. Low beams should be a pink wire throughout.
