I need help in trying to determine what the cause is for my CI error message. originally it had the CA error, i checked and replaced the belt since it was broken. Now i get the CI error roughly at 69-71 seconds into the diagnostic mode. I was also able to determine that the motor and pulley assembly can spin freely with out the belt attached. once the belt is attached i can spin it freely clockwise, but when attempting to go counter clockwise, the belt is very hard to turn.. seems like it's brake is engaged. any thoughts on what i can check?
