YM1110D Won't Charge

[OhioBruce]

Thanks, Coy. I'm going to go ahead and get a new battery. There is no sense in trying to milk this one for another 6 months and this tractor won't see steady use. I have a motorcycle trickle charger. I'll install a wiring harness and use it on the 1110d.

Excellent thread! I will use the info to try and diagnose my 186D when I get back home!

Good luck.
I suggest a new thread if you have issues.

As Coy said, please start a new thread with YM186D in the title.

I have one too. The Charge light seems pretty random. Sometimes dim, sometimes bright, sometimes off, as I described before. My use is at lower rpm than most, pulling the watering trailer from tree to tree then idling at each tree while I pull 8 amps for the watering pump. Its a boating sump pump, submerged in the IBC Tote. Despite this use and the random lights, the battery always tests 12.6 volts or better so I ignore the light. But it is a little concerning.

I would like to see a new thread concentrating on YM186 - YM1510 charging.

I still have some randomness too.

I installed a new sealed battery and have been using my tractor some. My granddaughter drove it around the yard at a little over idle and the light stayed on the whole time. I'd rev it up a little to get the light to go out, but then it would come back on.

When I used it to haul firewood the next day the light stayed off. I varied the engine rpms, but didn't rev it too high.

That sounds like a poorly designed or poorly manufactured voltage regulator. If you go back to page 3 of this thread and look at message #27, I went into some depth about how these Yanmar voltage regulators work. Please read though it before you worry about a lamp flicker. Yes, I wrote too much and much of it is kinda technically boring, but the info is good.

Bottom line is that I think the regulator design is clever, but to work right it needs to use very high accuracy components and to redesign the circuit that drives the charging warning lamp. Both of these things would fix the lamp flicker, but would raise the price of a replacement voltage regulator.

If mine ever started to flicker the first thing I would do is mount anaccessory old style analogue voltmeter in the dashboard. Simply connect the voltmeter across the battery terminals. Now if the warning light flickers you can watch that meter and see if it is staying above 13 volts. If it is, take out that charge warning light bulb and carfully put it away somewhere it is more useful. Like in your toolbox junk drawer....

I hate idiot lights. They tell you next to nothing.

Nah. My simple-minded approach: So long as it always cranks vigorously ignore the blinkylights.

Darn, my CHG light came on and the battery keeps going dead in the past 2 weeks. Looks like I'll be reading this thread from the beginning. Bad enough since owning the YM2610, both birds and mice loved to make winter nests under the dash panel with all the wiring. Thought I had all that checked a year back while repairing the decompression pull and replacing all the dash lights. Then late Spring a chipmunk ate thru the right wire on the fender for the yellow light.

I wonder if Fredricks used licorice flavored wiring during the rebuild, too many critters have taken a liking to it. :laughing:
