Thanks everybody I worked through your suggestions and found the problem. The
50 amp plug had been replaced by the previous owner and not secured so the wires inside the plug had worked loose. A good outcome thanks again

SUPER!

Cannot switch from 50amp,it does not change when I try

IF you are on 50 amp service, you CANNOT change the amp setting. Are you on 50 amp service? On 50 amp service the amp draw meter will also be blank. It only shows amp draw on Genset and less than 50 amp service. Now, the way your Intellitec "knows/sees" it is on 50 amp service, It "sees" the 2 phase 120 Black and Red power input. Since those 2 leads are out of phase, that is how the Intellitec knows it is on 50 amp service. Now, you indicate you are on 20 amp service, and it shows 50 amp. That IS strange. What type of 20 amp are you on? Home outside receptacle? You can reset the Intellitec system by just disconnecting shore power and turning the battery disconnect OFF for 10 minutes then back on. That will do the same thing as pulling the fuse on the Intellitec module to reset. Doug

I should have mentioned, IF you have done nothing to the Intellitec control board or the breakers in the breaker panel and this problem just came up, the odds are the Intellitec module board is bad.

Thanks for the update!

The wall outlet power in the drawing is called uncontrolled circuits. These only come from the circuit breakers and are not through relays in the Intellitec unit. This means you have power from the cord to the box and through the breaker panel. plug a fan or light into one of the outlets and see if the power you read with the cord plugged in will actually run something.

The generator power goes through the same wires as the cord to the board out of the transfer switch, if it works on the Generator, the problem has to be on the cord somewhere. Check where it connects to the transfer switch.

Referencing manual supplied by jyrostng, check the 3 amp 120 volt fuse. in the EMS.

Check the breakers on the inverter.

This sounds similar to a problem we had years ago while traveling to Alaska. After several days of trying different things, we were advised to make sure everything was screwed in tight in the electrical panel of breakers. Nothing appeared to be loose but we tightened each one by one. After that the EMS worked correctly again. We never really found anything that we could point at as being the problem but evidently something was not making a good connection somewhere.

I think the Intelitech is just not indicating correctly. Sounds like it's doing what it's supposed to when connected to a 15/20 amp circuit. Can you manually switch it to the 20A setting?
