Re: A curious situation...

even though this should be impossible to mess up since it fries the jags:

are the input voltages to the jag connected in the same way? (+ to +, - to -)

if power input to the jags is the same, I would test the same jag with different motors, this would confirm whether the problem is with the motor or the jag.

if the same jag induces different directions in different motors, the motors are to blame.

if the same motor turns different ways under different jags which have the same input voltage and signal, the jags are to blame.

let us know what happens, i'm curious!
