Newbie: Glow Plugs - should they get red hot?

Hi all

Glad I found this forum I've had a good rumage for the answer to my question but thought I'd ask directly for a clear answer.

My problem is with a new car that I have just purchased. Its only a cheap one with a .15 engine with a glow plug stuffed in the top.

I have spent the lst few days running it in slowly and took it for my first razz on the beach yesterday for a full on rumble. Now that was all well and good but I thought I'd bring it back and adjust the factory steering settings and stuff (so it don't go in circles no more!). But now I have come to restart it I can't get it going.


I have made sure there is plenty of fuel in the pipes and plugged my glow starter in but to no avail - not a puff of smoke even.

Now I'm a mechanic at heart so I thought I'd go through the basics - took the glow plug out gave it a few turns (to get any flooding out) and tried again - still nothing.

Now heres the questions.........

Firstly a simple one. 1) How long should the starter need to be plugged into the glow plug for it to 'work'?

and

2) Should (when out of the engine) the glow plug get red hot? (because mine doesn't)

Ta

OK so I'm a dufuss

of course a glow plug should glow

I've checked and there is no electrical continuity between the terminals of the plug so it must be knackered, yes?

Anyone got any tips for the maximum amount of time a glow plug should be connected before it burns out (like mine)

It should glow bright and true as soon as you attach power. I have used plugs (in airplanes) for a year with no issues. I have also had piped motors that plugs lasted 6-10 flights on. All in the setup, and the heat of the plug. Colder plugs last longer, but some engines won't run well on them.

Sorry I don't know how long they last in cars!

i have had a glow plug in mine for about a gallon of fuel, and i think there was about a gallon used be4 that
as soon as i put the glow starter on the plug, mine will start, and usually i wait a good 5 secs after it idles steady to take it off(time to extend the transmitter antenna and toss starting equip outta the way) and take it off but somtimes leave it on slightly longer in colder/worse air conditions in which the engine does not idle as steady
normally though, as soon as u put the starter on the engine will start, and as soon as it starts u can remove the starter if the engine is not out of wack w/ the tuning
