Hi,
Working on a TMZ 50. Its spitting out a code 0003-- "Down only mode"... We have checked continuity on the out rigger switches back to the control board. It checks out fine. The bubble level is reading 2.5V on the X and Y-axis. It is stuck in "down only mode". The service manual breaks it down to a leveling issue. The outriggers switches function as they should. The bubble level is output is 2.5V on either axis as should be the the turn table switch, the main boom and the platform switch which are in series function as expected. We can level the base manually but we still do not get any upward movement at all. All down functions work fine. Last year we got alarm beeps while in the air, It came down fine and we never again got any upward movement..
