True or False

I have heard of people cycling there glow plugs by turning off the key when the WTS light goes out then turning it back on. My volt gauge stays low when the WTS light goes out indicating that the GP are still on after the WTS light goes out so would it not be better to just wait till the volts go up before you turn the key off and on?

That's exactly how I do it on the rare occasions when my truck is in < 0° weather. I don't have any particular reason for it....it's just how I do it. For the most part there is no reason to cycle them at all assuming the GP system is working properly.

the GP's stay on for a timed amount that is totaly unrelated to the WTS light, its just a light for people that dont know they have to wait.......

when it is real cold I wait a good 30 seconds until I crank on it, works alot better.

Cycling the GPR while its on just shortens the life of the GPR.

A trick that a diesel mechanic taught me up here in MT was to immediately crank the engine over for a couple of seconds to get some fuel into the cylinders, then shut the key off, turn it back on and let it run its normal cycle. This has made a difference for me in sub zero weather, the engine just lites right off instead of cranking awhile. Just my 2 pennies.

your still cranking the same amount of time, just glow plugging before or in the middle of crancking. same load on the starter, or more since your cycling the solinoid twice instead of once.

It is against the law in Montana to transport a female sheep in the cab of a truck unless there is a second passenger present.

Cmon kawa, I'm the guy who grew up by you. I was imported to MT not to be a sheep farmer, but to help keep that second passengers hands off of the sheep riding b@%^h! I am a sixth generation Californian, just freezing my butt off in MT.
