Okay. My glow plug system is working, everything checks out but the truck still won't start without a fight on cooler days (+20 on down). My brand new glow plug controller is letting the plugs cycle just long enough to let the tips start to turn orange and then it shuts them off. It does the same thing on each of the shorter cycles after the intital time when you first hit the key, just long enough for a hint of orange then they shut off. At best only the very tip (3/16 of an inch) actually turns orange. Is a proper system supposed to heat more of the plug? I looked on the kennedy website at their quick heat plugs and they show almost the entire end glowing, easily 4 times what I am getting. I can only get this amount of glow if I jump the plug across the battery for 10 seconds. Do the kennedy plugs react in the time my controller will allow, roughly six seconds.
Is there a spark plug that will actually react quick enough to warm the cylinder in the programed time frame the contoller allows?
How do I set up my truck to bypass the timer on the controller and hold the plugs on for a longer time. I have seen the posts regarding cutting the blue wire and putting it to ground to extend the glow duration. Can this mod be set up to allow normal system operation and the occasional extended glow time with a push button? I need to be sure my truck can start if I end up in an area without power to plug in after a cold overnight.
I am currently using Lucas DSO94 plugs which were in the truck when I bought it. I did buy an Autolite for fun to see how fast it would heat, no improvement over the Lucas. I set the Autolite across the battery for 90 seconds and it didn't burn or swell, the Lucas lasted 15 seconds and died.
Thanks in advance.
