What is the make and model of your EMS system?
What is the model or part number? Did you check the fuses on the controller module?
There are fuses ON the control module..........check those.
When I get home from work soon I can grab a manual and diagram for you on this system.
Yes, I get that......but, there are fuses ON the control board AT the module as well.
I will be home in about an hour and will try to get you a manual for testing.
