Charging problem

[gbirky]

Soundguy and Keoke,

Thanks for all the discussion. I found it very useful. I still don't understand how this thing must work - and I doubt we'll know for sure. The explanation of the two possibilities - elegant, and dirty but simple - both went over my head.

To answer a few more questions: I actually have two YM1110D's. This one had half of the wiring fried, but still intact enough for me to figure out how it was wired. I rewired it. The other one works, and is wired the same.

That said, I can remove the VR from the tractor that works to make sure this one does also. I will of course get the OEM part to fix it.

Bruce,
Thanks for the part number. Do you have any specifics on this part other than it is a B+ type regulator. By the way I don't know what "B+ type" means.

If you could provide some type of drawing to show how it would integrate into a charging system such as the one on this tractor, it would be very useful indeed.

Jim, what did you do about your alternator/regulator problem? As I recall, you started this thread sometime last week.

 

[Soundguy]

If you do have a regulator to swap with, that is a good place to start trouble shooting. Also, check the voltage levels ( raw ) at the other dc generator and see if it is also getting 30vac with no reg attatched ( noot hooked up to the rest of the system of course ).

My guess is, is that if you have a working model to compair to, and it is wired as your diagram shows, that your 'regulator' is probably shunting the excess ac voltage ( possibly through a load ( resistor ) to ground... Without further info.. hard to say.
But in any case.. with a working comparison model, you should have no problems isolating the failure.

Greg, the bottom line is that IF your system is wired as shown and the VR is disconected, the system should charge at MAX current. This is only IF you have a good alt and the wire "R" is well connected to bat B+.
The VR in this system can only work as a "trimmer" system dumping excess voltage to gnd through a hi wattage resistor. In no way is the VR in the position to shut the alt down completely. Disconnect the VR and see if system works, if it doesn't, forget the VR and look at alt and circuit wiring to bat.

cheers,

Norm:
I haven't done a thing yet. I have been amused at how far this thread went. It's very educational, and goes to show how much knowledge some of these guys have. I sell Yanmars, and took a reg. off a junk 1401d, but that didn't work either. I guess both might be bad. I might eventually try another, or just buy a new reg from Len Shaffer.

The regulator has 3 terminals. Two are labeled B+ and connect to the two wires coming off the generator(dyno). The last terminal connects to the + battery post. I connect the last terminal to the ignition switch so that the regulator is only connected to the battery when the switch is on.

Thanks,

Bruce,
"Two are labeled B+ and connect to the two wires coming off the generator(dyno)."

Do you mean the two AC wires of the generator?

Because I have two wires from the "alternator" - but they really come from the diode bridge - one is DC, the other AC.

If the two B+ are the AC wires of the generator, then this regulator includes the bridge rectifier (diode pack) as well as the regulator. Do you know if it includes the rectifier?

It sounds dirt simple if this is the case. The 15 Amps is way more than my alternator puts out.

Yes, 2 AC wires from the generator. Kohler also offers a 5 amp regulator that I have used with small units like yours. I will look up the specs on the regulator when I am back at the shop tommorrow. I really like things dirt simple as I am sure most everyone does!!

Thanks for listening,
Bruce

Bruce,
THANK YOU! I am an engineer, who unlike many, believes that the simpler the solution, the better - provided it gives the desired result.

SIMPLE IS ELEGANT! At least in my book.

Thanks again,
Greg
