I have checked and there is 12 volts on the terminal panel on the rear of the coach that turns on and off with the jake brake switch by the driver seat. I am not sure where it should go on the engine. Does any one have a manual for the cummis 903 or knowledge of how the jake brake should be wired and function. Kind of scary going to Maine last year with out it. Thanks Jack
