That happened to us not quite two weeks ago. The combine started a fire off the left side of the engine compartment on a 2388. A Case IH engineer came as well as a fire investigator who works with combine fires and they both attributed it to static electricity. Classic example of an exhaust lit trash fire. Radiator fan is on the right,blowing to the left right across the red hot exhaust system and exits on the left.

The combine didn't receive any damage but it did burn close to 600 acres in rugged terrain. The engineer was working on grounding the moving plastic on the combine to reduce static electricity. The combine was a brand new 2388 and that was the first field it had been in and had a total of 10 hours on it.

Should not have taken that engineer long to ground all the moving plastic ,I looked at a very late model 2388 today and noticed that it does not have even one plastic panel,moving or otherwise,all are steel?

They also checked other 2388's in a field and one had a high reading and the investigator said it would start a fire and the operator said it had already had 2 fires this summer

I checked your post and it also seems to have a very high reading. (see below)
