Can anyone tell me what sensors turn on the audible alarm on a 1640. This is the alarm that comes on when you turn on the key but goes out when the clutch is pushed in during starting. Once the combine starts the alarm comes back on after about 5 seconds. I'm asking for my neighbour..he borrowed a wiring diagram but it's not clear all of the sensors that turn it on. Thanks in advance.
Unless I'm mistaken the alarm that comes on when you first turn the key on is for low oil pressure (the oil press light will be illuminated). There aren't any warning lights lit up when the alarm comes back on, are there?
