You got it! Don't really need an LED to tell me that. The only need for a LED I can think of is if you have a manual switch for the GPR. Then I would want a spotlight shining right in my eyes!!

You can see it in a volt gauge. Most can feel the motor surge when the electrical load falls. Its another sign of working GP system.

This post is a good read even today. One question: Isn't there only one GP per cylinder? Does someone have a 16 cyl PSD?

But yes, you are correct... 1 GP per cylinder.

It's not like it's a little wiggle that's hard to notice on the voltmeter... Turn the key on, hear a KaTHUNK and then voltmeter drops quite a ways.

I kinda like the idea and may end up rigging something up for it... I have a cali truck after all... so using the GPR shunt would allow for a bank to bank reading, but all it would give is the amperage the glow plugs are showing... so you would have to convert it with resistors somehow to only work when there is a certain amount of load on the GPs....
My check engine light tells me that I do not have enough current running through my drivers side glow plugs.... So an LED may not have any practical meaning though...
Hopefully that CEL will go away this weekend!

think he wanted one for injectors and one for glow plugs....

I've had an LED sitting around for months now... never got around to installing it yet. I'm running an 01 non-Cali PCM and re-wired my GPR so I get to do it the easy way now. If you can make yours work having one for each bank let me know, I think that would be awesome! It might be a good way to figure out which bank has the dead glow plug w/o having to have the codes pulled.

As fast as they fire, they would be on all the time like status lights. haha.

Well. Remember, its Rog, and he's a bit crazy.
A status LED for the GP relay isn't a bad idea, but unnessicary.
I'ma wire in the GP off and on switch. I am sick of running my already bad GP's while the truck doesn't need them.
2 mins on no matter what, how annoying.
I'm not going to go as far as jim with the coolant method.
