Help a nOOb please!! TA05ifs problem

[mc_mclovin]

hi ppl,

Have just finished building my ta05ifs (totally stock) and everything seemed to be fine, until i added the electrics...

now the problem i have is the rear wheels dont turn!! all the drivetrain is running fine, both belt going as they should...and the front wheels seem to be fine, turning as expected....but the rear wheels simply dont turn! i can spin them and they then start turning, but as soon as any pressure is applied (even the tiniest bit) they stop turning! the belts still move as i expected, as to the front wheels!

So please ppl....HELP!!
