Why is it I can put my D size battery glow starter on a glow plug and it glows but if I hook a D size battery strait to the glow plug it does not glow? And yes it grounded and correct polarity.

Polarity does not matter for glow plugs.
The D dry cell has a higher internal resistance.
. . . it can't deliver the 2-3 amps needed to make the glow plug glow.

Ask your doctor if your heart is healthy enough for Radio Control Helicoptering.

So my Associated D-Size Glow Ignitor GT2 has a something that increases the amps?

Yes, and also increases manhood and prevents solar eruptions ;-)

...but seriously - it's the battery that makes the difference, IMHO..

The GT2 uses a NiCd (Nickel-Cadmium) cell, it's not a carbon-zinc dry cell.

... or if you take out the battery and connect it directly to the plug,
then either it's not connected properly or the connection is giving
too much resistance (too small contact area or oxidized metal)

The battery is a 2500mh nickel metal hydride.

NiCd and NiMHd are in the same performance category with NiMHd being a bit lighter.

The only explanation is that your non-starter connection (where you put a battery straight onto the plug) is faulty. Can't be anything else

Make sure you've got a complete loop for the current to flow around.

Yes, it should work. Your batter is dead or your connection is bad/dirty and wont pass the current.

I agree either way should work and polarity has nothing to do with it
The end of the glow driver is nothing more than a pos neg connection pos to inner portion neg to outer portion of glow plug. it is just a short between the little wire inside the glow plug like how a flash light works the bulb being the glow plug.

Fly it ! Crash it ! Rebuild it ! Repeat as needed !! Everett

It works, you are doing something wrong. I have used a AA in a pinch and works just fine. For my savage truck I typically dont take all my gear, I just take my d cell igniter.

I would rather be in a boat, with a drink on the rocks, then in the drink, with a boat on the rocks!

It was the wire I was using. Brought some high quality wire home from work used it and it glows very bright now, thank you for all the input.

If my memory serves me right you can use a AA battery to light a glow plug . I think my old Cox cars have a clip that clips on the head and glow plug that was ued to light the plug . Oh well you figured it out .

If you're not living on the edge you're just taking up space !

Glow plug
Another example of open mouith and say something stupid. How does that same battery light up a light bulb? I guess the internal resistance changes?

Think before you speak ! Break the glass on the bulb, It will still light until the filament burns away due to oxidation.

It works, you are doing something wrong. I have used a AA in a pinch and works just fine
I also can attest to the effectiveness of my homegrown ignitor which consists of a D-cell battery. Total cost in parts is about $6.00. I got tired of having to charge my glow ignitor and the inconsistent contact it made as it sagged under its own weight when placed on the end of an adapter or the glow plug itself. My setup is as follows:

Adapter setup
Qty.
1- radioshack solder alligator clip-attached to glow plug
1- solder ring terminal- attached to crank case through bolt
2- 4 inch strips of 18 gauge(overkill but its what I had) speaker wire soldered to ring terminal and alligator clip- then soldered to each terminal on female deans connector
1- female deans connector tie wrapped to landing strut

Ignitor setup
Qty.
1- $0.99 radioshack D cell alkaline
1- male deans plug
2- 8 inch strips of speaker wire soldered to each end of deans, stripped back and electrical tapped to either end of the D-cell. Used longer wire on battery so it can rest on table while starting.

I just plug the two deans together and start her up.Best ignitor setup I've ever used. You can even make the chime with your mouth and make everyone think you are balling enough to afford switch glow.After a decade passes of using the D-cell battery you can go to a flea market and buy another one for $.10. Bling on fellas! Bling on!!!
