Unable to load the program when the sensors are connected

hi,

Robot model : 4wd1 autonomous

I tested with two basic programs which are present in website(i.e., aprotut1.bas and bb2tst01.bas), it is working fine ( sensor are not connected). But when i connect the sensors and try to run the same programs it shows following message " Atom must be connected to Auto detection".
I guess the program is not loading in the Atom. Could you please help me out to solve this problem.

thank you,

First thing that jumps out at me, is there a wiring problem that causes the Atom to not power up when the sensors are connected? Do you have a volt meter. You need to check the output of the 5vdc regulator to ensure it’s 5vdc.
