Do you know if it ever worked in your combineIJ No F3's around hear but if it were one of the larger combines you would have to bring module to a dealer with module tester. I hope you didn't adjust something you shouldn't have. Might want to bring tachmeter with also to get idea if ground speed output is working. Does ground speed work consistantly on monitorIJ Maybe unhooking the two modules and using some connection cleaner you may fix the problem. Do you have a neighbor that would let you try his modulesIJ Good luck
