Chris,

If you have checked your wiring and it= is all ok, then disconnect all the plugs that go to the EM-2 so that you are o= nly running with the EC-2 and try it to see how it runs.  Be sure that the plugs from the EM-2 can not touch and short out on anything.

If that doesn=92t work, then set the EC-2 back to the factory defaults and try that to see if that corrects your problem.

Failing that, plug in the spare EC-2 t= o see if that works.

 

By checking all the wiring, you have eliminated a miswiring.

If your EC-2 works without the EM-2 in= the system, you know the problem is the EM-2 or the serial connection.

If the spare EC-2 works, you know the problem is your EC-2.

 

Good Luck!
