Suburban SW10DEL quit working on gas, just fault light

We went out this last weekend and when we wanted some hot water, I switched it on, the fault light immediately lights up. Appears to be a control module gone bad? Anyone have any good troubleshooting ...

go outside measure voltage accross legs 2 and 4 if you do not have 12.8 or higher it will not open the valve but if you hear it sparking your control board is working look for the soarce of low voltage
