Thank you Engineer-Joe for replying to my post. I have checked out the links you provided and they explained the problem.
I looked for an update to the PS3 firmware but going by the date listed, it appears the firmware available on the MTH web site is the original Firmware that was loaded on the engine at manufacture.
I'm not worried about it beaause I am sure the voltage on track is no more than 18V.
