Post your questions or problems you are haviing with your Yanmar tractor here.
Guys, I'm now working my way to the electrical part of my tractor. None of the gauges work except the tach. My alternator isn't working either. Could these be related. And really no need to send wiring schematic, can't read it.

Unusual, but if not, looks like that is your starting point. Here is a thread on TBN where I changed the bearings in one. They are rather simple. Yours is the same as mine was on my 2002D.

I don't know about that but if the dynamo is not putting out that would still seem like the starting point for repairs.
so, to be clear when checking wires out of dynamo, meter should be on AC, and probes should touch the two spades coming out of wire. THere are two connections in the terminal. Either one is fine for positive and negative with probes. Sorry about all this, but I am not electrically technically....
Ok, Winston and Aaron. I owe you an apology. Dynamo is working. Checked with a new meter and it IS indeed putting out. 12v at idle up to18-22v at higher rev. Now, is there a way to check regulator out put?
I am sure there is a way but I am certainly not an electrical person. I would make sure the the voltage from your dynamo is making it to the plug at the regulator. If that checks out and you are still not getting charge to the battery then I would probably assume the regulator is bad unless your wiring is in shambles. Take this with a grain of salt and hope Aaron or someone with more electrical knowledge happens by.
Any chance a wiring diagram is out there? It might help me figure out if I have ANY power coming out of regulator and it may help show where my regulator goes to battery. It must hop on at the stater where + wire come from battery. There is no other wire going to my battery.
The 2010 is in Japanese. Also attaching a 226 in English. Maybe looking at them side by side you can interpret some. I know they are not to clear but best I can do with size requirements.

I was actually just looking at the 226 I found online. I think given that the gauges don't work as well, and I have power out of the dynamo, I'm inclined to thing the regulator is bad. It looks like the regulator has a red wire from it to the starter where it jumps back to to the battery thru the positive wire. Since I have nothing at the battery, it must not be coming from the regulator.
