Has any body heard of doing a LED light for the GPR so you actually know when it is ready to start. Learned that WTS light going off does not mean that it is ready to start and wanting to look into this.

 

Sure but havnt done it yet...search "GPR" mod or someone will chime in soon enough that knows something

 

Ya- I did mine about 2 years ago- Just tied the onto the hot post(outlet side) of the gpr, fused it with a 1 amp fuse & put a radio shack led in the dash.

 

It's real easy, just did mine a few weeks ago. Hook a wire up to the big post on the GPR that doesn't have power when the truck is off. Mine was the one on the right when your facing it from the front of the truck. This way when the GPR turns on, your LED lights up.

Fuse the wire with a 1-3 amp mini fuse, run the wire to the cab, hook up the LED (Be sure to test to make sure you got the pos. and neg. right), drink beer.

 

GPR LED won't tell you when it's ready to start. It is an indicator to let you know the GPR operated.
The LED illuminates as long as the GPR is operated. The GPR, depending on oil temp, will stay operated
for up to 2 minutes per the manual (some say they have seen their's stay opreated longer).

This is the typical installation. Where you mount the LED is your choice.

 

It is one of the easier mods to do. Just get a 12v LED and wire the negative to a good ground. The positive side goes to the GPR relay (glow plug side). It is best to install an inline fuse right off the relay (1 amp fuse) just in case something goes haywire.

 

i love mine.

 

I didn't know my led wasn't 12v. I hooked it up and it lit up for a second. Haven't replaced it yet

 

it will also let you know the relay has gone bad, vs the wait to start or gp light won't. it lights no matter what.

 

I picked up a 12v led from adavance,and I picked up the chrome led holder from Radio Shack,sorry,I'll have to get part #s from my other computer at home...

 

Be careful when you do it and don't do what I did! https://www.ford-trucks.com/forums/1...ml#post9996444

 

I just had an idea. How about wiring the light along with a tiny volt meter/amp meter combination gauge? We use them in aircraft and would prevent all that relay testing in the future. The gauge has one needle and two scales. and a push butten to select amps.

Man I Love This Forum!!!!! You guys are GREAT. Would I ground the light to a universal ground on the truck, kind of like the one my radio is ground to?
I had been going thru a winter of hard starts. At first I found GPR was bad and replaced it. Still was having problems and recently learned that the WTS light did not mean that the GPR had kicked off. Started timing a minute + before starting depending on temps. and it has been doing good. Wife drives it more than I do and she has been waiting 2 minutes. Thought this light would do good.
Thanks for all the help.

 

Do I have to wait till the end to drink beer?

 

Unless extremely cold 2 minute wait isn't necessary. Waitung that long can be a catch-22 situation. As the batteries age waiting 2 mnutes can drain the batts to the point where you may encounter a no start due to not having 10+ volts while cranking. At 15° degrees I wait 40 seconds (approx the time it takes fuel pimp to cycle twice). That is what works best for me. Less time at warmer temps. Each truck can be different so you need to experiment a little with your wait time. Also if you wait until GPR releases and do not cycle the key the GPs will not be on when you start. It helps if the GPs are still glowing at start. Less smoke as well.
