Ok I am curious what the purpose of a Barometric pressure switch is? Reason for asking is this. Our M108S is used in forestry applications. It has a custom cage and push blade on the front. After transporting the tractor about a 100 miles away for a pine tree mowing job the light came on as soon as I unloaded off the semi. I immediately shut it down, checked all fluids (which were ok) then started calling our Kubota dealer back home. They told me that that light means that a something has triggered a sensor that it was possible that it was low brake fluid or the water in the radiator was a little low to check those things. They told me that the machine could still be used just to bring it in when it gets back. So I ran it like it was. There was no noticeable lag in power and it ran flawlessly through out the entire job. When we finally slowed down I took it to my Kubota dealer. After sitting for almost a week they finally hooked up to their computer and it threw a code for the alternator. Now I called myself testing the alternator with my meter tester. It showed 12volts when turned off and 12.9 volts when running. I never had to jump or charge the battery the entire 7 months it ran after the light came on. (Keep in mind this is a cab tractor with AC & Heat). The dealer replaced the alternator and the light was still on. They hooked it to the computer again and it threw another code. This time they said it was a Barometric Pressure sensor. They told me that this sensor is inside the ECU and the only fix was to replace the entire ECU to the tune of 2500.00 plus labor. But they did say that I would still be able to use the tractor like it is the light just would not go off.
I'm jut looking for a second opinion. The light I'm describing is a small red circle with a exclamation point in the middle (!). Its is not the big circle in the middle of the dash that usually is followed by an annoying beeping noise.
Thanks in advance for your thoughts.
