APM 2.6 AR6100e not connecting

Works perfect telem.,OSC,gps,etc. when I do not connect the receiver…

When I connect the 5 channels to the AR all goes dead no data sent by telem or usb.

When I connect the servo leads 1-5 to the AR receiver I get no connection to mav,when I disconnect all 5 leads all goes back to normal except no receiver!

If I provide power and bind to the receiver first would that help?
