Revolution won't power up

Hello All,

 

I have a Revolution that is not powering up. I have swapped out the power supply module and the control data module as well as the SCC board... Checked that power is making it into the power module as well...

 

Any thoughts?

  • Do you have a working S4R to swap its PSU and MCC out with? 

    Most likely then its a cabling problem - either the connectors 

    are connected backwards or the cables are damaged?
