50amp Smart EMS ???
Got the rv out for the first time this season and have already ran into a problem. I noticed my AC units would not come on after I got set up at the CG. Everything works except the AC units and water ...

I pulled the board out this morning. It is an Intellitec 50 amp Smart EMS. When i plugged it back in the indicator lights came on for about 2-3 seconds and then back off. Unplugged it and plugged it back in again and the same thing. It lit up for 2-3 seconds and back off. Everything works on the coach except those that go thru this panel. I checked the 5amp fuse in the fuse panel for the EMS board and it is good. I am going to look for the fuse Doug is talking about. Thx for the replies.
If it powers up for a few seconds, then the Fuse on the EMS board is good. Intellitec is a bad system in that ALL the controlled relay's for the shed appliances MUST have the Intellitec board operational. Failure and the 120 relay's fail to close and allow 120 power to the appliances. From you description you need a new Intellitec EMS control board. The remote display rarely fails. Your only solution until you replace the Board is to label EACH 120 wire at the relay's on the EMS control and wire nut the 2 wires together for each appliance. That bypasses the EMS board. MAKE SURE YOU HAVE THE 120 POWER OFF IF YOU DO THIS. You probably have 4 relay's maybe 3. The wires to be connected together will be next to each other. The link I sent is NOT for your specific system but for a 2 appliance system but the schematic shows how the wires and relay's work. Doug
