05 magnum 330 won't run

[atlpa]

Have a magnum had issue with the ECM a year ago had that replaced. Worked great, couple of months ago went to ride, turned key, and got nothing, battery is great and charged, replaced the ECM again and still nothing, the lights do not turn on or anything, and suggestions? Thanks

Check to make sure your battery cables are clean and tight. Might have a loose cable somewere. Just a starting point.
