yes, i have power to the switch... i have no power to the 2 pac brake relays because they are not receiving signal from ECM.. in this coach the signal from the ECM supplies power to relays then in turn, sends power to solenoid to activate air cylinder for exhaust brake. I will post the exact cause of failure when cummins completes the repair......weather its the ECM or a broken wire in the connectors to the ECM.....stay tuned !!
