i always new that w.out the right volatge there could be problems, but when i was looking thru my book trying to find something esle i noticed it says right it there that it has to be 12.8 volts or engine failure or ruff running can orcure. just shows how much these newer bikes are fincky i guess.

 

I entered the diagnostic mode inadvertantly the last time I started up the ATV. For those who have not tried it, there is a voltage meter on the LCD display that will give you a reading on your battery without the engine running. It also gives a reading with the engine running. Sort of neat to see how things are doing.

 

This is only on EFIs only I imagition. The processor needs voltage to operate right. But in reality, it will operate at a lower voltage, because when you are starting, your voltages are problably around 10.5 v till the alt starts working.

 

Hey Sheepdog, how do you get in the Diagnostic mode? I have an '05, 700 efi. Does it hurt to "accidently" get it into it?

 

actually the 450,500,and 700 carb require 12.5 volts/ the book.

 

no it doesnt hurt to be in diag. mode. w/the bike in neutral, and the key off hold the override button in and turn the key on. once screen is ativated let go of button and your there. bayyery volage is first.
