Locomotive Is Too Heavy When?

I'm adding some weight to a Athearn SW1500 to increase it's performance. So far I have added about 1 1/2 ounces and it seems to be improving, but how much is too much? I have seen mentioned in one of the MR locomotive reviews(Athearn GP60M) that adding weight can be done, as long as the wheels spin before stalling the motor. Can you do this by holding the loco stationary(not applying downward preasure) and see if the loco spins it's wheels while advancing the throttle? <br /> <br />Also, I'm assuming the reasoning behind letting the wheels spin is to keep from burning up the motor. If I advance the throttle and it won't move because it has too many cars coupled to it, would it still hurt it for just that short time the motor is stalled?
