BTW... It's the same principle as a gasser creating 60,000 volts from the coil to fire the spark plugs.

It does that from a 12 volt system.

 

That would be the principle of the autotransformer. Has nothing to do with zener diodes or voltage divider resistors, or the like.

Just the same, the glow plugs DO draw a very considerable amount of 12 volts DC amperage, even though they are not even needed until the temperature drops to serious (by SoCal standards) low temperatures.

As a result, I think I'm going to wire up a glow plug disable switch for all but the coldest starts. Save them coulombs! A warm-start mod! Yea, THAT's the ticket!

The parts used in any type of transformer, step-up transformer, regulator, inverter or converter ALL use a zenor diode and/or voltage divider resistors in order to perform the function they are designed to do (if the funtion is to alter the frequency of the input source).

 

Cookie!

You're a mod. Put a stop to this lunacy!

This is getting WAAAAAAAAY out of hand!!! ;-))

No need for cookie to stop it...

I would have dropped it long ago, but for the replies.

Talk amongst yourselves, I feel no more need to be an educator this evening.

 

Don't go away mad. Just g......... ;-)))

Now you've made it personal.

That's a shame.

It's too bad that some people have a problem with the 'exchange' of information, if it happens to differ from their view, and have to take it to a personal level.

 

I'd love to see where you people are getting the idea that the glow plugs are 115V. Both my Ford shop manuals, and my digital multimeter prove you to be incorrect.
Pull a valve cover off, unplug a glow plug, hook one test lead to the plug, the other ground, and see what you get(you could just check it at one of the valve cover connectors, but, that only takes seconds instead of at least a good half hour... LOL) Any T444E powered truck I've ever checked the glows on ran a 12V system. The glows may be rated to handle 115V(I doubt that, however I can't say I've ever checked) but, just because something is rated for 115V doesn't mean it runs at it. Only the injector solenoid voltage is stepped up.

Anyhow, FWIW, my 00 PSD would start on one stock sized battery without a hitch so long as it was warmer than about 50 degrees. Cooler, and the voltage draw was too much to start it with the glows on, and the system voltage would drop below the 10V minimum that the IDM requires to operate, but, if I waited for the glows to shut off, the second the voltage rose above 10 volts indicated on the AIC, the truck would fire right up. Below 10.00 volts, the IDM shuts itself down so it doesn't burn itself out. Truck will crank over all day, but, never get any fuel, and never fire.

 

That's the nice thing about this forum. Facts are facts, not "points of view". You're not "educating" anybody, you're confusing them. This information is not open to conjecture or interpretation. What you are telling folks is wrong information, and that's just not right.

Gotta' call 'em as I sees 'em!

"wrong information" from your point of view

facts is facts, I get the facts, I pass them on... I don't make them up.

"The glow plugs operate on 115-volts DC. Do not pierce the wiring insulation or use a conventional test light on the glow plug wiring, as you could recieve a severe shock"

Just because you don't see how any voltages on a 12 volt system could be any higher, dowes not mean that they aren't.

 

No, not my "point of view" at all. Your whole gibberish about zener diodes and voltage dividers was just plain wrong. The whole thing about 115 volt glow plugs was just plain wrong, too.

Whoever you are quoting is wrong, too, and that doesn't make you right, just someone following someone who is wrong to begin with. Get your facts straight before coming on here and attempting to be "The Educator".

There are lots of voltages on my truck that are higher than 12 volts. Heck, on occasion the voltage across my speaker leads is higher. But not my glow plugs.

If you are a troll, time will have a way of weeding you out of this forum. In the meantime, as we used to say on Usenet, PLOINK!

You could go with 1 battery probably a group 8 D is the equivalent but finding a place for it under the hood is a problem. You just need the amps. The Voltage is just a quick conversion. 10 to 1 if it takes 10 amps 120 volts it equals 100 amps 12 volts. If you lived in a warm climate like Mexico or Hawaii you could get away with 1 of the Batteries they install. But for most of us those few cold days would kill it. Let alone you guys on the East Coast or Mid West.Hope this helps to explain it to you.

The glowplugs are 12 volts,sometimes under.But the injecters on the other hand are 115 volts,look at the sticker on the engine or even get a manual.

TrvlnP8 is right about one thing. As long as we refrain from insulting each other, then we simply are on opposing sides of a technical discussion...which is what this forum is about. It would be way out of line for me to close a thread just because somebody's technical opinion differs from mine, no matter how off base it seems.

TrvlnP8.

The warning about not piercing the high voltage wires originally appears in the Injector driver module removal section. The red striped wiring harness that is referenced in the glow plug removal section is only there because the IDM wires run through the same harness. If you follow 82F100SWB's advice and put a voltmeter on the system yourself you will realize that the glow plugs are indeed a 12v. system.

It's your turn, where you at? I got a kick out of reading this post. It was like a soap opera. Pretty good
