it almost seems as if there is a bad ground to the electrical box
i can can run a wire from the - side of the battery to a ground in the grey box
and push the lanyard switch in and it will start (the start/stop button has no affect on it at all... pushing it does nothing) when i let off of the lanyard button it shuts off as expected. if i try this again it will not work unless i take the 5 amp fuse out and then put it back in ( it does not blow so i use the same fuse) and it just does all of this over again ...
