60G glow plugs run about 10-12 Seconds of glow time for an average cold start iirc. I know a 60g glow plug is just starting to get good and hot in about the same amount of time as it takes for a 9g glow plug to explode. So glow times changed considerably in newer trucks with the 60g glow plugs from the factory.I was reading those articles in the cetane thread.
That one page was on glow plugs.
The writer said at 30*F that the GP cycle was about 8 seconds.
I have never timed mine but, it always seems like it is about ten or thirty minutes. But of course, that is My impatience timer ticking along. It actually does seem like more than 8 seconds.
There is also instructions for a GP bypass option using a three way switch, temperature sensor and a relay.
That seemed interesting. After I have had the engine of My truck running, shut it off to go into a store or, etc, when I get back to the truck, twist the key, I always wait for the WTS lamp to extinguish before going to start mode.
On several occasions, I have twisted to start position before the WTS goes out. It has always extended the crank time by a little, not much but enough that I think I am better off burning GPz than I am the starter.
