What is the resistance of the wavy shunt on the GPR controllers?
And that is exactly why I was trying to find a way to go ahead and keep the glow plugs on for the factory time duration, and just limit their exposure to more voltage than the factory figured they would be exposed to. A custom tune can also terminate the glow plugs from staying on, without even...- Burnt

Smog check...a bad omen (california)
@bob_442 (In a southern Buford T Sheriff drawl...) "What we have heeeeerrre is a case of 'Engine Change' and a change in 'Motive Power', we reckon." Remember, that California is only interested in smog checking what actually produces smog, which is the engine. So they follow the year of the...- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
My truck indeed has that dual alternator option, and Ford did indeed test that very scenario. And this must be why Ford commands the second alternator to remain off until the glow plugs are commanded off. So having two alternators is the same as having one alternator, as long as the glow plugs...- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
As the screenshot says, "If battery voltage is abnormally high, the duty cycle is shortened to extend plug life. The glow plug relay will only cycle on and off repeatedly if there is a system high voltage condition greater than 16 volts." So while the PCM is monitoring system voltage, it is...- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
I'm not at all confused. I'm in the exact right place. It is the IDI's who have the controller I was interested in. The Powerstrokers know nothing about it.- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
That aspect of short cycling the glow plugs, as a protective measure to prevent burnout from over voltage, is one of the aspects that attracted my interest in retrofitting a Glow Plug Controller in lieu of the regular relay that is currently installed. I've since learned that folks have a lot...- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
Wow... I'm so glad I joined OILburners.net. Just imagine being stranded out in the middle of a desert, where you can't even see the horizon cause the air is wiggling so vigorously from the heat rising off of the parched dry hot sand. It's so dry, that there is no sweat left in your body to...- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
I'm looking for some means to reduce voltage to the glow plugs... but not all the time. It isn't necessary to reduce the voltage when the glow plugs are pre-heating the cylinders prior to the engine starting. However, it is necessary to reduce the voltage to the glow plugs once the engine has...- Burnt

What is the resistance of the wavy shunt on the GPR controllers?
I don't have a GPR controller that has the wavy shunt resistor, so I can't measure myself. But I'm curious, and while searching for more information about this era of GP relay/controller, I read a comment that said the folks at OilBurners.net know more about the glow plugs and controller of the...- Burnt
