Bobcat S650 ALJ820443 sn glow plug relay constantly energized

[Sloan Kettering]

Any help would be greatly appreciated.

Unit drained the battery, error codes E000676-04 & E0005324-03, glow plug relay was hot to the touch, wire 1300 which triggers the relay is constantly hot with 12 volts even with ignition switch in off position. While testing with no schematics I unplugged ignition switch, battery lead at alternator, control box above park brake solenoid, ignition relays in the fuse panel, individual relay wire-tied to the main harness above the two control modules on the left side of the machine in searching for the source of power energizing the 1300 wire.

if no one has messed with the wiring, and if a wire is hot when the switch is off, I would say the switch is bad. well unless it is a always hot wire like memory for radio or such. but not a glow plug circuit. pull the glow plug relay to see if the battery still drains as a temp. fix.
