Re: Ism oil pressure Reply #21 – January 25, 2021, 01:24:54 pm Pulling the oil pan isn't hard but be prepared to possibly twist off a bolt where pan bolts to aluminum tranny housing. Had to pull mine as drain plug was stripped out and yes I twisted off one bolt at the tranny but enough was left to weld a nut on and get out. The machine shop installed the drain plug kit from cummins so all is good now.My ISM runs low oil pressure also. It goes down when I turn the lights on also. Doesn't worry me since that is caused by voltage drop at the dash, haven't figured that one out yet. Quote Selected

I was quite concerned about it but I don't think I'm As much. I would like to have a second mechanical gauge but Would have to find another place to tap into it. My Bluefire never shows anything that bothers me. I could also have a wiring issue or ground like yours. I've read several posts about solving weird stuff with proper grounds. As Roger mentioned could also be a failing converter box. Good fun either way.Thanks Scott Quote Selected
