Hello and Welcome dwingert2,
In many cases electrical failures on Yanmar can often be attributed to loose, corroded and poor connections to both the ground and positive wiring. If you dedicate a few hours pulling, cleaning and checking all of the connections (including corrosion inside battery wire insulation) to the block, battery and frame, it very often fixes the problem.
I知 all for keeping my Yanmar tractors as original as the day they were built?ut the alternator upgrade is something I致e been seriously considering because it eliminates costly components in the charging system, produces more than adequate power and only minimally requires some fabrication and a longer fan belt. Just waiting for one of the tractors to fail with the current limiter-voltage regulator before I make the jump.
Good luck.

a short
well i disconnected all wires and wirewheeled them and whatever they were attached to also disconnected the ground to the frame and cleaned it and the frame the rear flashers were both broken so i completely disconnected them and all wires going to them to rule out them to not be grounding out then i hooked the battery back up and the alternator/generator started smoking again so now im lost.
could the regulator be bad and be backfeeding the battery into the alternator causing it to smoke? or does this just sound like the alternator is bad
also its a 2610 (grey market) the manual we have says it is a negative ground is this correct? we wondered if it was a positive ground and were hooking the battery up backwards the old battery was returned for the core and we cant remember what was +/- on it

I'm sure it is negative ground.
If the alternator starts smoking when you connect the battery, I would agree with you--something is wrong with the regulator, assuming it is wired correctly.

I think Kenmack has it right, you have a major short in the system.
Maybe a wire finally wore thru the plastic, or a mouse chewed the wires.
Are there any mouse droppings on the engine? look carefully
Do as Mark says, spend an hour tracing all your wires in a well lighted area.
Thats where I would start.

well i put the gm alternator conversion on that someone posted a link to from ebay and it seems to be working well we had narrowed the problem down to either the generator or alternator because we couldnt see anything shorting out and i cleaned and replaced all wires and was still getting smoke from the old generator the only problem we still have is no headlights doing the conversion you disconnect the plug/harness that is plugged into the regulator does anyone know if the headlights are wired through this harness? if it is then that may be the reason for no headlights before if the reg. was shot and not putting out the correct power to the headlights and now that it is disconnected it deffinatly wouldnt work we are thinking about putting some chevy headlights in it and just running all new wires for them. sorry for the long post.

I dont know how they come wired but, you could just run a hot wire from the batt to a switch (fused) from a switch to the lights
just an update ive been using the tractor with no problems since i put the gm alt.on fires rite up charges properly so i would recomend the ebay kit and also just fyi when i bought the kit from the guy hes local so i just went and picked it up he said he didnt have any on ebay at them time because it was winter and that once it started to warm back up he would post some more for sale.
