CUCV Ignition Buzzer while heating plugs

Good morning everybody i'm new of the forum. I own a '85 6.2 diesel CUCV. Since Yesterday while warming plugs before the wait Yellow was going off also a buzzer was playing its noise.

Buzzer sound could be the solenoid mounted on the fire wall under the hood. It could be a seatbelt buzzer a key in ignition buzzer. Unsure what you are experiencing.

The buzzer you're hearing is the seatbelt buzzer, it's just a coincidence that it times out with the glow plugs.

Mine does the same. Buckle the seat belt and try it.

Look at your fuse box. At the top you will have a black rectangular box (looks like it has a speaker in it) [It doesn't but it looks like it does]. That is your seat belt buzzer and activates the in dash seat belt light. If you don't like it you can just pull it.

My seat belt buzzer never worked. So, it not working does not affect anything.
