Legacy Diesel Issue (Southern Heritage)?

This is normal for this engine from what I can see on the catalog description.  Later versions of Legacy Engine electronics keep the Cab dark until "startup" but earlier versions the Cab comes right on at power.  The small crackle in the speaker is most likely the audio electronics powering.

Unless the crackle is on going after power is applied, I think you're good to go.  Does it operate fine otherwise?

Thanks Marty!  Yes, other than the cab light coming on and the initial speaker crackle, everything else runs fine.

A good way to know for sure is, since the introduction of the "sequence control" the startup has turned on the Cab lights.  If this engine doesn't have sequence control, it has the older electronics, and the lights will come on with power. 

I think you are probably good to go and your engine is performing as designed.  I have several that are pre-2011ish that act the same way.

On the Legacy GP9 I have, the cab, headlight, and number boards come on when I power up, but I haven't noticed any sound until I press Start Up, but I'm using DCS too so that may make a difference.

Some engines, regardless of the manufacturer, will "pop and crackle" a little when power is applied.  I suspect that is what Jacob is catching.

Again, thanks all.  I did noticed that sequence control wasn't present when pressing and holding AUX1.  It sounds like everything is performing as expected and has the older electronics.

After I made that statement I ran the GP9 and found that ONLY the number board lights come on when I turn on the juice, my 3rd Rail E7 does what I said in my previous post.  Neither gives me any "crackle", but again, I'm using them under DCS.

When I press Start Up the GP9 headlight and cab light come on, but the cab light goes out when the engine starts moving (really like the sounds Lionel gave this engine).

Maybe I'll pull out the CAB1-L and see what happens.
