Glow plug solenoid

Have an 01 7.3. How long after the truck is running is the solenoid supposed to stay energized?

I think it it up to or more than 2 min depending on temps.

Some time

It depends on the PCM and sensors and such.

What about putting it on a switch so I can turn it on only for it to start? I really dont think there is a point in it being energized after the truck is running. Mine is staying on well over 10 minutes after the truck is running.

How do you know it's staying on that long?
And yea I guess you could but I'd hate to forget that switch and it stay on all day

Well when I start the truck up I watch my DMM voltage on the side of the solenoid where the glow plugs get power from and it never goes below source voltage. And about the switch, if I have an LED indicator on it and I leave it on. Well I guess I just have myself to blame..

The switch could be helpful for sure.
And if there is voltage still reading after 10 minutes, something is wrong.
