My K-Line K-29802 PA-1 ABA diesel set has dual motors in both A-units. The motor in the rear of the lead A-unit has stopped running. The other three motors are still running normally. I've examined the wiring to/from the problem motor. I don't see an obvious issue.
This set has years of run-time on it. Do the "maintenance-free" can motors sometimes just fail? If the motor has failed, would the simplest solution be to just remove the the motor? Wouldn't three motors in an ABA set provide enough drawbar pull for most consists?
