The cemetery I used to work at has an '08 L3940 that's randomly shutting off. The guys say it showing "error 84 accel ng" on the panel and flashing a red light. I've been searching around for a list of error codes for this but can't find anything covering this issue. I'm trying to diagnose it over the phone from two hours away so any help is appreciated. They may have just smashed the kill switch wires under the seat but I'd like to know what the error code is pointing to. They said it starts right back up every time it shuts off like that.
