Allen Bradley micro 820 no LED,s lit

[GazzTee]

This unit was removed from one project where it had perfomed nicely. Wired into simulator and we have no signs of life no LED,s lit power supplies checked is there a reset or some obvious checks we should cover

Remove everything but the power, just a wag but if you have a short it maybe dragging down the power, so discounted everything but the power and see if the it powers up if it does then your issue is in your simulator

Have powered the unit up withou any inputs or outputs still no indication of life yet moments prior to changing to another project it was operating ok. No signs of poor connections or faulty components.
