Reply to "MTH Z4000 onboard breakers not tripping"

Thanks all! I appreciate all of the valuable input. I noticed today that a derailment did flip on the 'overload' light and shut the throttle off...or at least I'm assuming it did since the locomotive probably wasn't making contact with the central rail anymore. The FET explanation is perfect. Thanks! So I'm assuming the red 'overload' light is in essence a breaker or fail safe then? Like on the lionel gw-180 when the light blinks red during a short? So, even if the circuits on the back aren't tripping, the internal stuff is protecting. Also, I am considering doing an in-line breaker just for the heck of it. Never hurts to be safe. What amp should I use? Thanks again!
