First off hello to everyone one the site. I just Bought a new to me yanmar 1500D. I'm having trouble getting it to start in this cold weather. I bought it 2weeks ago and haven't had it running since I bought it. I put a brand new battery in it a few days ago but when i crank on it it seems like its not turning over fast enough for it to start, acts like a weak battery. I know the little glow plug thing in the air breather is workin because i can remove the cover turn the key to the left and watch it get red hot. What could the problem be, i just dont think its cranking fast enough and by the way the new battery is 700cca. Could there be a bad ground or weak starter or what. Hopefully someone can help me and i hope i didnt get burned on this thing. Cause like i said i cant get it running now, i hope i didnt waste $1,700 dollars on it.

use the decomp lever as well
Cold weather plays havoc with troubleshooting a starting problem, it's always much easier in warm weather.
First off, I'd make sure that the electrical connections (both ends of both cables, and the starter connection) have all been checked and cleaned, battery topped off with a fresh charge.
Where has it been sitting, outside, in an unheated building or a heated garage? If it's outside, put a tarp over it and get some heat under it to warm things up a bit. Even a 100 watt heat bulb will do wonders if you've got the tarp tucked down good. (Make sure you've got everything set where you don't start a fire!!)
Did you change the oil and filter after you got it? The oil could be thick enough to slow it down, especially if it's in an unheated area.
But Clemsonfor nailed the big one, all other things being right, the decomp will let the unloaded engine speed up enough and build up oil pressure that once you release it, the flywheel inertia will help get it started.
I can understand your frustration, I just bought another new to me tractor that is just sitting in the barn right now because it's too darn cold to get out there and start fooling with it. But spring will be here soon (I hope)

do you have deisel fuel in the cup on top of the motor? thats suppose to drip down on to the "glowplug" which is know as thermostat since its not actually in the cylinder.

On your battery cables. I had problems and heard quite a few people also miss the Ground to the Chassis. IMO. it's worth removing and cleaning it not just checking to see that it's tight. Or just the connection on the battery. I believe I replaced the Whole Neg. cable come to think about it. Never had a problem with a slow starter since. BTW I use to live on the OH. River just the other side from you. So I know how cold Ky. gets. Which is probably working against you without a doubt unless it's indoors. I learned to like PBR. and even RW&B

Since this thing is 30+ years old... if it cranks slow, go feel every connection point in the heavy 12v cable AND the ground circuit. It is very common to have a bad, corroded connection where a heavy wire meets the terminal at the end of that wire even when the wire and terminal assembly looks pristine. Power will be lost as heat at the corroded point, as a clue to replace that cable.

I put 5050 antifreeze in it. I have been trying to get it to start all day now and it will not start for anything. Im barely getting puffs of white smoke when trying to start it and the decompression lever doesn't help any. I dont get it i just had it running 3 days ago. I need to get it running in a hurry so i can move some firewood
