vermeer (BC900XL vanguard 35engine) purchased 3 months ago .Had some water in fuel issues but the current problem is the thing wont start without a jump boost from my car but the battery is fully charged. Even bought a new battery but the same issue arises. Painful. Does anyone know where to find the error codes that show on the diagnostic display? i get *521288SPH 4FMI Hold to run swith voltage below normal or shorted to low source* I cant find explanations anywhere from the web or instruction literature provided. Vermeer sales rep is never available by phone and my town is a good distance from service centre-300kms so i cant front up
