Thanks - thats where I found the code....

I managed to take off the main power relay, and powered it up - it gave me a new error code - 3-8 which isnt listed anywhere I can find....

I bought the 2500 manual online - and this does list this error code as main power fail. Its not the same machine, but is similar. Might be the oil pressure switch weirdly

I saw a post by someone that had a similar problem, and it turned out water had gotten into a connector, once he brought the mower to the dealer, the problem disappeared by itself just by time..
