One from Bigdog
They sending new one free.
Told them check out before they send.
Hope new one works.
I just know the engine light stays on when i ride it. Goes off at idle, but from red light to red light comes on.
How did you get one from Big Dog? They went out of business in 2011.
Unless you mean Kansas Motorcycle Works or "Big Dog is Back" as they like to call themselves now.
If it is anything other than CompUFire or Cycle Electric I would not install it.
You should use CompUFire but in your case you will need the 3 phase 40amp system due to the additional power needed for the fuel pump, efi etc.
