Farmall 706 D282 Glow Plugs all blow out at once.

Yep.
2 months ago i bought a $90 set of 6 glow plugs for my 282. all works great up until now, Today I went to start up my 282, and I held down the glow plugs for 60 seconds, and cranked it over and it almost took off. i heard a few fires while i was cranking it. then i stopped and put two 10 amp battery chargers on. one charger on each battery. and let the glow plugs rest for 4 minutes. i did another 60 seconds of glow plug heating cycle and it ALMOST started. all 5/6 plugs were working too. after 3 minutes of letting plugs cool, i hit the button and no glow plug power. i blew every mother fuc*er out.
Anyways, I'm trying to learn from my mistakes here. do you think it was the to 10 amp battery chargers that did the glow plugs in? or am i holding glow plugs to long? i hold them down for 60 seconds at a time then let them rest 2-4 minutes. how long should glow plugs last?

I did have the block heater plugged in for an hour and a half too.

I changed my 560 to the Autolite #1111 Powerstroke glow plugs. They will fit the injectors after running a 3/8 X 24 fine thread die over the metric threads the plugs come with. Also need to replace the wire ends to fit the bullet type ends the plugs come with. Now it starts with 15-20 seconds of glow time for faster starts.

Okay. So when you said i have to run a dye/tap over the autolite 1111 glow plugs, do i just need to re tap the threads of the glow plug or do i have to tap the WHOLE glow plug as in its whole outside diameter is to big? or is it just the threads that are too big? thanks

OPINION: I don't think you did anything wrong. A 12v glow plug in a 12v system should glow indefinitely, till the battery's dead. Try checking the injection timing. Do a compression check sounds like it's starting harder than it should for being plugged in .As a point of comparison, ether and/or incorrect timing is murder on 7.3 PC glow plugs.

Battery chargers and cheapy glowplugs are not a good combo, but two 10 Amp chargers shouldn't have done THAT much damage.

I replied to your post on the Farmall Forum suggesting some quality self-regulating GP's that are a direct fit on your engine.
Other thread...

I was curious what the Autolite glow plugs looked like so I googled them, and they get terrible reviews! That would scare me away! Shouldn't your tractor start without glow plugs if it's plugged in? Our JD will start at below 0 deg. F without any heat.

The thread area needs the die ran over it so the plug will then thread into the injector.

One must keep in mind here that glow plugs have a sorta time limit on them as to how long they should be on and if they excide that time limit they will burn out . I fought this problem on my one friends New Holland skid steer . When he bought it it was hard starting and found that two of the four glow plugs were toast , so off to the New Holland dealer to get the correct glow plug and for the small price of like 37 bucks a piece we installed all four NEW . These glow plugs cycle according to out side temp , so when you turn on the key it senses the temp and the glow plugs will stay on longer on a cold day up to 14 seconds and when you hear the CLICK then you start . Well He has two LX 665's BUT they do not both have the same engine . The older one is the best one and has given the least problems and i have never changed the glow plugs on that one . The newer one i can not count the times i have changed them . and when they go out it is always on a day well below 0 . Well after freezing my fingers one tomany times to get it up and running so the cows could be fed i started looking into WHY , we were using factory OEM parts but they kept burning out . There has got to be a place to get them for less money , so i started looking and the one ORiles that i deal with has one guy that will actually go digging to find you what you need and also get ahold of the company that supplys the part to figure out the problem . The glow Plug in question were made by Boush (sp) and he called the tech dept . and put me on the phone with a tech guy and he enlightened me . He told me that the glow plug part # that New holland was usen had a BURN TIME LIMIT of OH guess what 12 seconds ON TIME BUT the timer was Burning them 14 seconds. and they were of a like 7.4volt ( don't hold me to this for the gospel ) and that they should turn red in like 6 seconds . Well i spent about and hour talking to him and he came up with a glow plug # that would fit and it had a 19 second Burn limit and would turn HOT Or red in like 7 seconds . So when asked HOW MUCH he tells me that my cost would be and i was waiting to hit the floor and look for my inhailer and take two nitro pills and he said 7.48 EACH NOT 37.48 but 7 . 48 So that meant that we were able to keep 120 bucks in our pocket rather New Holland's pocket . I said send me eight . I had them the next day and installed four and put four on the shelf . I have not had to replace one yet and that was three years ago . Just like on the POWER STROKE they run basically a 6 volt glow plug on a 12 volt system on a timer for fast heat up and the timer to take out the IDIOT holding the button . Where on a glow plugged tractor engine you are the timer on cycle timer and those glow plugs are of 12 volt . I stat looking at the cold cranking amps of the battery-s , condition of the starter ( is it turning the engine fast enough , Is the injection pump timing where it should be , Are all the glow plugs working , When was the last time the valves were adjusted . Once all that has been checked then we go deeper How are the injector cracking , what is the cranking pressure of the injection pump , what is the compression of the engine . When a D236-301 is working good they work well to a point till it gets cold then they can be temperamental . So just layen blame on the glow plugs might be part of the problem but there is more to it then just glow plugs . Then one must keep in mind that there is no two engines ever the same . As to why on your problem ????? as i can not do a hands on all i can do is throw some idea's and past experiences .

could be you may have hooked the battery chargers up wrong and shot 24 volts through a 12 volt system

The first couple years the 282 was used, several customers blew out all their glow plugs all at once. They cost like 8 bucks apiece in 1960 and customers were unhappy to say the least. It was always caused when using battery chargers. Your two ten amp chargers could have very easily increased the voltage to over 15 volts and that will take them out right quick. You learned an expensive lesson as did many. I remember two of the guys and one was through the roof and other just took it in stride. Just the way they were.

Now, you might ask, why did new tractors need battery charging. Usually trying to start them in cold weather but often just a lot of start and stop without getting charged back up and using wrong starting methods. At any rate, they had the chargers on them.

I know nothing about the alternative brands or sources of glow plugs for these engines and only dealt with factory type.

yes, even the old chevy 5.7,6.2, 6.5 diesels used 6 volt glow plugs an a relay timer. they cycled on and off to prevent burn out. and yes many factors for a good starting 282.
good compression, good injectors timing, battery, cables.and starter when all is in good shape they start very easy. they must turn over with enough rpm or forget it.
