Glow-Plug Relay L.E.D. ?????
So, for those of you that have installed this LED do you now wait to start your truck until LED light goes out? Why? If you start the truck after the "wait to start" light goes out but the LED has not are you causeing damage to your glow-plugs?

No.. ON pobably both questions..
If it is 20 below and I dont give a .. oh wait.. if it is 20 below, and I know I have had problems with weak batteries, I will wait for the led to go out. If I am having no problems I will fire right up when the wait to start light goes out. I am trusting the computer to know how long it should take.
If ( hasnt happend yet ) my truck doesnt fire up, then I am going to be looking at my LED to see if it has indeed fired the GPR, or the GPR is closing.
For the most part, Our trucks should be able to fire to say-10 with out a MAJOR problem, but why try it when we have the GPR and GP's

The easy way to tell when the GPR shuts off is by your headlights for those that do not have an LED. When the GPR shuts-off the headlights will get noticeably brighter!

If it's very cold(between 20 and 30 degrees),I usually wait about 30 to 45 seconds before cranking,if the GP LED is still on it's just putting heat in the cylinders after starting,which is ok.

I pretty much use the light just so I know the GPR is working. And also it's useful for those times the engine has enough heat in it that the GPR doesn't activate but that WTS light still comes on, I know there's no need to WTS. In the summer time I don't ever WTS anymore, I just turn the key and go.

Maybe they were talking about the 6 volt glow plugs which the early Fords used on a 12 volt system for faster glow time. If they stayed on for more than 10 or 15 seconds they could do some damage. VW Rabbits used the same ones.
On my old 6.9 I installed a glow plug indicator light for that reason, since I had heard of the glow plug controller sticking in the on position resulting in pieces of the glow plugs dropping off into the cylinders.
