Abstract: Methods for detecting a short fault of an alternator rectifier electronic component include sampling a field winding voltage or current signal of an alternator, during operation of the alternator, and determining a fault ripple period at which the alternator field winding signal exceeds a fault threshold. A short fault of an electronic component of a rectifier coupled to the alternator is detected in the event that the fault ripple period closely matches an alternator armature period. Alternatively or additionally, the sampled field winding signal is band pass filtered, and a short fault is detected in the event that an amplitude of the band pass filtered field winding signal exceeds a fault threshold. The methods can be implemented, for example, by an apparatus that includes a hysteresis frequency counter, a frequency comparator, and a countdown timer.

In one example, a truck includes an unpowered axle spring system that is configured to generate an overall unpowered axle separation force between a truck frame and an unpowered axle carrier. The overall unpowered axle separation force has a rate of decrease that increases past a first separation distance between the truck frame and the unpowered axle carrier. A powered axle spring system is configured to generate a powered axle separation force between the truck frame and a powered axle carrier. The powered axle separation force has a rate of decrease that decreases past a second separation distance between the truck frame and the powered axle carrier.

Abstract: Systems and methods (e.g., a method for controlling and/or operating a compressor) are provided that includes the steps of monitoring a crankcase pressure of a first compressor; analyzing the monitored crankcase pressure that includes calculating an average of the crankcase pressure over a time period and comparing the average of the crankcase pressure over the time period to a nominal crankcase average pressure; identifying a condition of the first compressor based on the analysis of the monitored crankcase pressure; and adjusting operation of a second compressor to compensate for the first compressor in response to identifying the condition of the first compressor based on the analysis of the monitored crankcase pressure. (The method may be carried out automatically or otherwise by a controller).
