Case ih 1640 headlights half working

elk1640 · Nov 7, 2017

Left 3 headlights not working on combine checked all wires and grounds still not working and the right 3 work fine. Any ideas?

I'm trying to remember when I had my 1660. Engine had to be running for some of the lights to come on.

Is there separate relays to run the lights on each side? A dead relay would provide the symptoms you describe.

How did you "check" the wires. Visual inspection doesn't mean they're ok.. get the voltage meter or test light out and you can tell where your problem is.

Do you have two switches, one one the dash and one in the overhead panel? I'm trying to remember but I had one that if you only had one switch on it would do something weird like only light up one side. You really need a test light or multi meter and start checking.
