LB1914 Glow Plugs

[lmbrsn]

I have a LB1914. Is there a way to check that all of the glow plugs are working properly. It has been cold in the mornings and when it starts up it only hits on one cylinder for a short while.
Thanks

Check the resistance on each of the glow plugs, they should be all about the same. Give me a call if you have any questions.. You get your loader working ok?

Jon: I show a 0.8 resistance across all three of the glow plugs. I don't know what they are suppose to be new, but they are all the same. They are a bear to get to. Yes the loader is working PERFECT. Thanks for all of your help. Jim

did you disconnect the strap going between all 3 of them. If not it will give you a bogus reading... .8 is low though. If i remember right they should be about 8-9. Also have you checked to make sure you are getting voltage to the glow plugs...you can use a test light for this.

Yes I disconnected the strap between them. I will check the voltage going to them. The relay clicks and the light goes out after about 10 to 15 seconds.

Any final analysis on this yet, I have the same tractor and it does exactly the same thing, mine is a 2003 model, just wondering if there is a common defect in a solenoid or something.
Sequence of events:
Turn key to on poistion, glow light lights
Wait 10-13 seconds, glow light goes out
turn key to start position and machine starts but good bit of
white smoke and runs rough for about 20 seconds.

I know something in the heating cycle isn't working, cause as long as it's above 60-65' the thing starts right up and runs clear and smooth.

the colder weather will effect the starting performance of a diesel. if its really cold you can pre-heat twice. I have been doing that lately.... been 5-20 degrees out the past couple weeks.

As of the 10th, I will have had mine for 1 year. Last winter mine operated just like Frank described. I also was told to let the glow plugs go thru 2 cycles. This seems to help some.

Not sure if it's just a LB1914 issue. I think it is a generic diesel thing. I own an LK3054 and usually pre-heat my plugs twice to start otherwise it cranks a long time and that's not good for the starter motor.
PS, my engine was brand new March 2005.

My CK30hst has a position between the normal glow plug preheat and start. When it's below 30 F', I let it do the normal preheat and then turn the key a little more to the manual preheat for about five more seconds. The glow plug preheat light comes back on. It starts everytime without a problem. I think from some other posts last year that not all the tractors had this manual preheat position.
I can just imagine how hard yours is to start without the glow plugs working properly. Good luck with the diagnosing but it seems like you are almost there.

My Mahindra fires right off in even the coldest weather. We do get cold temps in New England. It just seems unusual to have cold start issues.
I hope nobody takes this as a "mines better than yours" post. I have a 2810HST which has a Daedong (Kioti) engine. I guess thats why I find it odd that there would be cold start issues with your Kiotis. I would think it could be glow plug problems. One cycle is all it takes for me. I don't discount that maybe maybe mine is an exception but, I'd rather believe others have continuity problems in the glow plug circuit.

You might think about installing a block heater to bypass the whole problem. That is, if you have an electrical outlet nearby.

I really appreciate everyone responding, I have tried to pre-heat twice even three times, I don't feel it makes much of a difference!
Does anyone happen to have the spec for how much voltage you should see at the glow plug during the pre-heat phase??
Can I assume that the test of voltage would be volt meter positive plug to top of glow plug, negative plug to a good ground??

Just for Info. I have three other diesel tractors (All Kubotas) each has it's own little differences, but the significant diff. between all the kubota's and the Kioti is that all Kubotas have MANUAL pre-heat which I much prefer. Obviously I'm used to diesels and cold weather, and I'm sure the KIOTI glow-plugs aren't working correctly, just don't know the proper test specs for problem issolation.
All in all I like the LB1914 for what it is. Can't say that it is more reliable than the kubota's, since 2 of the Kubota's are 20years old and still run like new! But the Kioti is a tough little tractor.
Any information at this point is much appreciated!!!!

thanks everyone.
