GPR LED Mod = Good Troubleshooting Aide
Yesterday I went to start the truck and I noticed that the LED for the GPR was flickering very dimly then went out quickly. Truck started up fine though. This morning in between the rain I went out and tested for voltage, yup GPR gave up the ghost. Just for the hell of it I started the truck she fired up with no problems it is in the 50's here. I am so thankful that I had the LED to let me know of the failure. Once the cold weather hit I would have been dead in the water with a dead GPR.
For all of you that do not have this mod you should really consider doing it. Very inexpensive and easy to do but can save you alot of frustration in the long run.

There is Greg I will try to find it.
All you need is a 12V LED from Radio Shack a 1/2 amp maximum and a length of wire. Connect the LED 1 end to ground and the other lead to the load side of the GPR (the one without the rubber boot.) When your GPR is energized the light is on. You will be amazed at how long it stays on at times.
Here is the thread with the part numbers

Sounds good Jim, if we get together tomorrow maybe we can put one in my truck. I'll have to run to the shack and get the LED

It makes me smile reading about all of the folks that have installed the GPR LED. I'm very happy to see it identified a failed GPR. The original GPR LED is still in my truck and working like a champ. WMRiceman

Mark Thank You for pioneering this mod. IMO it is a mod that is a necessity. Yesterday my LED came on very dimly once then bright as day another time then not at all. I know that the contacts on the GPR are all arced out and not making contact as they should. All of this information because of a $5 mod
