I test drove an 1989 863 514440001 series yesterday and noticed a red trouble light was lit on either the the upper or lower right hand side of the indicator panel - the panel on the upper right side of of the cab. Sorry I can't be more specific, just noticed as I was getting out of the machine. Again, it was the light on the either the upper or lower far right side. And, it was red for sure if that is any help. We checked the engine oil and it was full (dirty, but full). And the hydraulics worked fine. I'm hoping that it is something as simple as the parking brake indicator - I set the brake when I stopped. Can anybody identify the top and bottom far right indicator lights on an 863? thanks,
