New - Sound - As is well ?

[Black06]

Noted an interesting sound while driving (radio must be off to hear), but almost sounds the same as the sound when the glow-plugs are heating - right before she kicks-over.

Does that same relay that fires the glow-plugs continue cycling during normal operation ?

Looking for some diesel education.

Thanks

No, and that is probably the relay kicking OUT when you get ready to start your truck. Or it maybe coincidental to starting.
