9500 lights

First off I would like to say hey to everyone and share the thought that I have gained lots of knowledge from this site over the last few years. I now have a problem of my own that I cant seem to figure out. I have a 89 9500 that's having issues with the lights. The flashers work fine, however any setting on switch that activates the headlights and taillights ultimately result in my lights flickering. For instance I was picking corn last night and the lights worked fine four about 45 mins to hr. Then started flashing and would stay off more than on. Sometimes it only takes a few minutes for the problem to occur and others it may take 30 40 minutes and I have run a few nights that I didn't have a problem at all. Any advice would be greatly appreciated guys. The board up by the tank has been replaced.

sounds like the relay has an intermittent contact, and or burned contacts, also check the ground for that circuit and the relay ground source. so many times we chase the positive side of these circuits and in actuality the ground may be the issue, in this advanced computer age with so many systems running a 0-5 volt reference any resistance and poor grounds are multiplied...
