Show/hide table

The relay for the air shut off valve needs to be replaced on certain C9.3, C13, C18, and C27 Industrial Engines, CX31-P600-C9I Petroleum Power Train Packages, and C15 Petroleum Engines. The existing relay may not close when exposed to medium wavelength frequencies from other equipment due to an electronic magnetic interference in an emergency situation.
