Spyder dead even after replacing battery - ideas?

[DGoebel]

So help us out here, many would love to help, what year Spyder RT do you have? (Since you posted in the RT Shop talk forum).
1. Replaced battery with fully charged battery. You've done that.
2. Checked battery voltage in Spyder. Check at battery terminals, check at battery end of cables themselves.
3. Checked all fuses in fuse boxes.
4. Checked kill switch operation, switch in Ride position.
5. Ignition key to On position, no lights, no dash, no anything?

* Additional Double checking: polarity correct? Nothing wiggled loose when installing?(tight space & short cables can be aggravating) key turning ok?(not too loose or hard in either direction)
