Hi folks, I am new to the POG, i have been reading all the posts new and old but this is my first post. I purchased a 1992 Prevost Bus in AZ and it shutdown about an hour from where I picked it up. I had to have it towed and stored for a few day till i can get to it to start troubleshooting. I was traveling up the grade out of needles and the coolant temp got almost to 220. I know that is too high, the Bus needs a complete flush of all fluids which i plan to do once I get it home to Los Angeles. I felt the power drop off, then the tack dropped to zero and i got onto the shoulder. Seems to me if it was a sensor shutdown it should have reset itself once things cooled, but it didn't. I put a jump box on the engine and it turns over fine, just no crank from the Key or switch in the back. I have all dash lights etc, just won't crank. An interesting thing i noticed, is I have no red light on the shifter. Hopefully this is a clue for someone. Any help would be appreciated.
