Voltmeter Lag
As a relatively new owner, I am learning as I go.
I have been noticing that after startup my voltmeter reads kinda low (but well within the "normal" limits) then after about a half aminute or more, it kicks up to slightly past midrange.
My question and/or presumption is this: The glow plugs are still operating for a period of time even after startup?.?.
Seems like a logical deduction, just hoping for confirmation.
I am a high school shop teacher (small engines) and this diesel stuff fascinates me! I have learned more in the last month reading the posts on this forum than I did in 5 years of college!
Thanks fellas (and ladies)

Does anyone know if there are two different barometric sensors available for these trucks? One for a truck originally delivered to a low altitude zone and one for a truck originally delivered to a high altitude zone? My glow plugs always stay on for a long period of time, regardless of outside temp or engine temp until I get to an elevation lower than where I live (at least 6000ft and lower). My truck was originally delivered to Post, TX, so I'm sure its not running the high altitude package.

I have never heard of a different barametic sensor, i realy don't think it would matter, it not so much the air pressure, but the air temp that tells them when to activate.
Check this out, will be my mod for this weekend.

I HIGHLY suggest everyone look over his site, the guy not only has a sweet truck but a TON of cool mods also.
