Hi all.....I just purchased #599, a 2001 triple slide w/ DD Series 60, working my way home from OKC to Michigan. I stopped at Newell Coach today, got a little "Newell 101" from Randy. SO many controls to learn. Randy told me it was ok to run down the road with the "Detroit Engine Pre heat" switch in the on position, as it would act as "motor aid" water heater. When doing just that today, after about 5 hours of driving, a red "pre heat" light came on in the "warning lights" section of the instrum panel. What does this mean?  Thanks in advance! Bryan
