Ivan K Posted May 21, 2022 Share Posted May 21, 2022 I think to remember it as a turn signal "beeper", the one than stops the sound when you stand on brakes. Link to comment Share on other sites More sharing options...
granvillebarker Posted May 22, 2022 Share Posted May 22, 2022 Definitely one of the beepers, either blinkers, tag axle, or low air. I have seen two of them in my dash, there may be more. Link to comment Share on other sites More sharing options...
Busnut Posted May 22, 2022 Author Share Posted May 22, 2022 Thanks, I have something making a sound very fant sound (screeching sound) when my engine temperature is around 195 or higher. And the check gauges light comes on and off very fant as well. My engine does not go over 210 when going up a steep grade. What is the normal operating heat range for a 2003 ISM? Any ideas what to look for? Link to comment Share on other sites More sharing options...
Ivan K Posted May 22, 2022 Share Posted May 22, 2022 With my ISM, 229°F is considered "Most Severe Level" and I would get a Stop Engine light. My normal cruising temp is 187 and I keep it at or below ~200 by downshifting and speed control when needed. Your 210 should be alright IMO but i would not go higher, I am just babying it and also watching the boost gauge, still climbing better than most trucks or other RVs. I just don't want blown hoses, works for me with the pre-emissions engine. Link to comment Share on other sites More sharing options...

Older ones like ours will chirp quieter especially at lower voltages. There must be one tied to temperature too; its interesting to learn about alarms that may be on my coach that I have never heard in 19 years of ownership. Perhaps its in the manual or schematics. I should probably read it again. Link to comment Share on other sites More sharing options...

Mine is multitalented as it will produce all sorts of lights and warnings…LOL. But, I did get the prints for it from the vendor. It has many MORE alarm circuits that Monaco chose to use. As a comment, all the alarm circuits are “grounding” controlled….as in, if a component or a switch fails, the “home run” loop grounds out. BUT, on mine, the “Bay Door Open” circuit was installed with the wiring harness….but I don’t have the individual switches….one each bay. BUT there was a chafed wire in the engine compartment and it was full time. I finally isolated the area or the wiring cluster and played with it and got it shut off. My NEXT plan was to cut the incoming wire for that circuit at the dash plug…. i really think that some of these are different in that I have heard some loud one in other Monaco’s but mine is really faint….and sometime even road noise will drown it out for my copilots hearing… Link to comment Share on other sites More sharing options...
