Bear in mind that it takes no electricity for a diesel engine to run once it has been started. There is no ignition system.
The Alternator should be putting out between 13.5 and 14.5 volts and up to 15 volts when charging a depleted battery.
Without seeing your alternator I could only speculate that your description of the voltage regulator is correct, but being an '07 model it probably is an integrated system.

I use a Harbor Freight Quick Hitch. Takes about 45 seconds.
Sorry the link won't post.

Guilin made more than one model of tractor as I'm sure Fujian made more than one model of engine. It would be very helpful to those with knowledge of your tractor to know the approximate year of manufacture and the model number, as well as the engine model number and the number of cylinders. What color is the coolant pump?

I think I forgot to ask, but have you checked/cleaned the suction screen in the base of the shuttle clutch housing?

As for oil to use in the shuttle clutch to “get you by”, you can use ISO AW-46 or ISO AW-68 hydraulic oil provided it has an AGMA rating of 4 or 5. Anything less is your call. The reason there are many different oil formulations is because there are so many applications that have specific requirements. I believe it will be a long long time before “one oil fits all applications”.

Yes, those are the final drives if I understand you correctly. There is one on each side. There is a drain plug underneath the bull gear. There is a tattletale plug about mid point up the back of the housing – this is where you check the final drive oil level. The final drive oil is added by removing the larger plug above the tattletale plug. This is where the 85w-140 gear oil goes.
The transmission and bevel gear compartment (the Chinese call this the final drive, but it's not.) have a common sump and are filled through the transmission fill plug (dipstick) next to the seat – this is where the 80w-90 gear oil goes. Check the level by resting the dipstick on top of the case cover, don't screw it in.
The bevel gear compartment and final drives are separated by the steering clutch/brake compartment which should have no oil in it at all. There are large plugs underneath the compartments for checking this. Don't leave the plugs out but check them periodically.
Manuals are in the mail.

I was wondering if that TO-4 would be better in the final drives than the 80W-90 would be?
I repeat: 85w-140 for the final drives. These drives have very high tooth and bearing loading and require a fluid lubricant with very high shear strength (not grease because it isn't fluid). Caterpillar TO-4 is referred to as a “torque fluid”, which is mainly formulated for use in torque converters and hydraulic systems but does not have an AGMA class endorsement.
So to answer your question: NO! Don't even consider it in that application. But personally I don't care what you use for a lubricant, it's your tractor, not mine.
Question. What are you referring to as the “final drive”?
I can't send you the manuals unless you tell me where to send them.

Great…thanks! It has 271hrs on it, there is no oil in the left saddle bag and i don't have the owners manual for it. I bought it last fall and just started using it!! The track came off and i didn't notice it right away and it jammed and i snapped the final drive shaft…. just finished changing the new shaft!!
Track came off and it wasn't noticed. Hmm. Has 271 hours on it so then you bought it used, and since you didn't get manuals with it that suggests that the machine has little or no maintenance ever. Did you get a service record? Of course not.

All i could find for oil for the final drives was 80w-90…….is this ok for the final drives on this dozer and can you tell me what kind of oil goes in the dipstick at the back of the shift sticks?
Is there any other oil i can use in there cause i called all over town and no one carries…ISO AW 220 machine oil!!
80w-90 is fine for the transmission and bevel gear compartment. The final drives (one each side) should have 85w-140.
What kind of town do you live in that doesn't have a petroleum distributor or NAPA close by?
PM me your email address and I'll send you a parts and owner's manual. But wait. How did you order parts for your final drive?
The ISO AW 220 oil is for the shuttle clutch only. As a substitute you can use Caterpillar TO-4 or TO-4M, or equivalent.

It is a Yuchai YCT 306-S.
The forward dipstick is for the shuttle clutch, and it takes ISO AW 220 machine oil NOT engine oil, NOT ATF, NOT gear oil, NOT hydraulic oil.
The round black cylinder in the left saddlebag is a hydraulic accumulator.
The “thing” at the bottom of the hydraulic reservoir in the right saddlebag is the suction strainer for the tractor hydraulics only, not the shuttle shift.
Please answer my last two questions, plus how many hours on it, and did you buy it new?
