comment What do these lights mean?
It could also be a short in the brake light circuit dropping the voltage to near zero.

comment Power steering fluid started to leak after changing it
You can always try adding power steering leak-stop fluid to the system and see if that makes the problem go away. :-)

Except the generator does not need to provide enough power for serious torque, just enough to keep the battery topped off while cruising at highway speeds. So I think it can be a pretty small generator.

comment How do I remove the front axle of a 93 Honda FourTrax 300?
Those things will destroy the boot on the ball joint, so all the grease leaks out, followed quickly by ball joint failure...

comment Is it possible to have a manual transmission electric car?
The weight from multiple motors is offset by the fact that each one can be half (or with AWD, one fourth) as powerful and thus lighter, and the reduced weight from eliminating all the other mechanical parts.

Indeed, that's exactly the design I would do. Even for a hybrid -- the gas engine would just run a generator to make electricity, so in a sense you could call it an "electric transmission". I would also put the motors inside the wheel hubs and maybe even allow the wheels to turn 360 degrees for the ultimate parallel parking capability. :-)

comment Bad to run the car for a short duration, turn it off, and start up again?
@Johnny: You could always lock it by pressing the lock from inside the vehicle before you close the door, then just unlock it with the remote.

comment Scooter won't start
So far your answer has been pretty helpful. After lots of random tinkering, we've gotten it to start, but it immediately dies. I'm still trying to find a complete diagram of the fuel system, as there are a few components which I don't even recognize, much less know how to diagnose.

comment Bubbling sound from coolant and increase coolant liquid level
By the way, if using a test kit like the one Larry recommended, look for any, even the slightest, change in the color of the fluid. On a vehicle I tested which turned out to have a bad HG, the transition was only from blue to slightly teal, nowhere near yellow or even fully green. If you know what to look for, you can probably just observe the bubbling at the radiator cap and skip the test kit, but it can be hard to distinguish from just having air in the cooling system (which you'll have if the level is low).

comment Bubbling sound from coolant and increase coolant liquid level
I agree it sounds like a head gasket leak. Note that there are many modes of failure for a head gasket, and it's likely that the ONLY direction of the leak will be exhaust gasses into the coolant. This will be the case if the gasket is physically intact and maintaining a seal except under extremely high pressure at the moment of combustion.

comment Can I disable antitheft (PATS) on 03 Mustang?
I've always thought it would be nice to have an open-source/open-hardware ECU with an array of DACs/ADCs and easily swappable wire harness adapters to match up with any vehicle (and appropriate software on the board). :-) Then you could do away with this nonsense (and a lot more nonsense) by just pulling the factory ECU and dropping in one of these...

Thanks for the update. It looks like the manual you provided a link to might help.

There is a parts list manual, but it's just very poor drawings.

comment Scooter won't start
We have the manual that came with the scooter, and it doesn't contain anything about diagnosis or repair. As I mentioned at the end of the question, I've been unable to find any third-party repair manual, so help finding one would be a good answer to the question.
