I bought an 8670 about a month ago and it only had one battery. I installed two with new cables so it would start easier when cold. When I put
in the new batteries it now shows the dummy light for plugged air filter (I put new air filters in it) and the oil pressure bar just blinks and shows
the corresponding error codes. I looked at the schematic and it looks like the oil pressure sensor and air filter sensor are powered from the
same line. Maybe it's just a coincidence that these errors stared showing up with the new batteries. I installed a new oil pressure sensor today,
with no change. I also had Ag Express update the modules and display and had them take the speed block off. They all tested ok according to
them last week. It sounds like a harness, connector or ground problem. Has anyone seen this before? Thanks Mark
