SP3020 Burning up multiple traction parts

I've been having problems with an SP3020-30 that is burning up traction parts. So far it's burnt out 2 forward contactor coils and multiple potentiometers as well as forward switches. It seems to always be the forward side that burns out. We're at a loss as to where to look to see what is burning them up. Has anyone had any issues like this before?

Fact of the week
Every year for Thanksgiving, the President of the United States is given a live domestic turkey by the National Turkey Federation (NTF). While these turkeys used to be slaughtered and eaten, during the presidency of George H. W. Bush it became standard practice for the president to issue a ceremonial "pardon" to the turkey.
