Hard Starting Boomer - HELP

[MeanGreen]

Wow, tremedous response. Thanks... I tried the voltage check this afternoon. It was showing about 12 volts (with the plugs still in the engine. I kept coming back to some funky reading I was getting from the first glow plug when I did the Ohm check. It was reading like 150+ which I assumed was due to how difficult it is to access this plug. My dealer tech told me they would fail open (like 0 on the ohm meter), so I assumed it was a fluke. I figured the next stop was at the dealers so I decided to get that last glow plug out. When I removed it I saw it had a crack in the element. I pulled plug number two as well and checked it on the bench. It seemed marginal to me (reading like .7 - 1). I took both to my dealer and his tech said both were bad. The tech was surprised the one read that high. Also, he surmised the failure of the first probably contributed to the failure (or very near failure) of the second due to the extra load due to the way the first failed. I got both installed this evening and turned over the engine. It fired right up. Yea! The good news is that since I had all the stuff off of the top of the engine I cleaned it up real good. Looks like new! Thanks to all who lent a hand.

Hi
how much did they charge you for the glow plugs. I checked a dealer a few weeks ago and they were asking about 140 dollars each don't remember the exact figure, I about had a heart attack when they told me the price. I was gonna buy a couple for spares but not now. I don't need to use the glow plugs for mine to start but I usually use them just because the book says do it. Maybe I should save them for when I really need them at the price they get for them.

Charlie.

YEA! You did a great job of troubleshooting. /forums/images/graemlins/cool.gif

Unless it's a cold Northeast Ohio winter day I start my Boomer without the assistance of the glow plugs. They shouldn't be needed for normal warmer weather starting at all.

A failed open won't be a '0' on the ohm meter.. it will be infinity.. a failed '0' is a short.

Not to nitpick you.. but the tech gave you vaugely misleading info...

Glad you got it figured out anyway.

Don't be fooled by a ohm reading on the glow plug as it could show you a somewhat proper reading when cold but as soon as you put current to it, it could very well open up if it were cracked or something. I've found the best way to check glow plugs is to use an amp meter. I know a lot of you don't have access to one of these, but it will tell right off if the glow plug is drawing close to what it is suppose to. The old Volts/Resistance=Current
12/ 1 ohm= 12 amps

yea, in fairness to the tech, he said infinity. I just said zero because my tester shows all zeros when you have no resistance. As for the price, they were like $24 per glow plug, nowhere near $140! I can't believe any of the NH models would have plugs that expensive. Maybe the parts guy pulled up the wrong number??? By the way, my tractor now starts on about the second turn of the engine.

 

[MeanGreen]

Just thought I would post a picture for those of you who never saw the 1925.

MeanGreen, are those recent photos? That tractor looks new to me. Very nice machine! /forums/images/graemlins/smile.gif

...and are you a Steelers fan? Your tag name has me curious. When Mean Joe Green was in school, he went to North Texas State Univ. which still calls itself "Mean Green" as a nickname. Then, of course, he went to play for the Steelers and they kicked the Cowboy's butt so many times I can't remember all the money I lost because of Joe Green and the Steel Curtain.

Anyhow, your name may not be associated, but it sure has a familiar ring to it. /forums/images/graemlins/cool.gif

Looks like it evolved into the "TC25D"....
It appears to be in nice shape.

Jinman, I took those pictures yesterday. Actually, I just took delivery today of a 1 year old TC24D with a 12A FEL and a new Woods 4' brush hog. I am getting the 1925 ready for sale. It was my father's machine, but it is just too big for me around my yard and I wanted a FEL and turf tires. I will post pictures of the semi-new TC24D this weekend. You nailed it on my nickname. I live 25 miles south of Pittsburgh, and I am old enough to remember the steel curtain days! It sucked to be a Cowboys fan back then (except maybe for one year).

UH??? yeah... 0 for NO resistance.. an open is (efectively) infinite resistance. And yes.. it is quite common for the cheaper digital meters whether manual, or auto ranging to show zero on the ohm scale on infinite resistance.. that's where a continuity buzzer helps.. but again.. that an dthe infinity sign, or a blinking zero is usually a feature only found on the higher end models. Analog meters should NOT show 0 ohms on an open.

markie, more like it evolved into the TC33D. The 1925 is a 34 hp unit. Just wanted to make sure nobody was confused by the "pre international" numbers.

 

[markie61]

I just assumed the "25" in 1925 was the horsepower. My bad /forums/images/graemlins/confused.gif.
