3520 Electrical problem

[Bruceva]

My 3520 all of a sudden will not start. Turning the key gets nothing but a control panel screen with all lights lit and blinking like crazy. The battery is fine and there is voltage to the starter. That's about as far as I am able to go. Disconnected the battery to see if the system would reset but no luck. Initially, I would get a message Error 57 which said something about no response from HST (or HTS?) but it has gone away.

Any thoughts before I start paying big bucks to the pros?

Thanks, Bruce

Before I took it in, I would try the following..

Hook up a battery charger, these things can be fussy....

Check all the fuses.....

Push the HST pedals down, set the parking brake, mess with stuff.....

Make sure your PTO and other switches are off, just because.....

Maybe even tow it ahead, move the tires?

I hope some others have some more ideas...

it does not really sound like a electical problem . it sounds like one of the safty switches has went bad of got dirt in them. the easy way would be jump them one by one. like seat switch and gear selector switch. and PTO switch.
