Last week while recovering from our tornado, my T650 track skid steer slid off a ledge and went into the creek. Over the exhaust and motor sounded like it locked up or quit before I could even get to the key and shut it down. My remote location took 2 days to get a recovery wrecker to its location. 6 pulleys and 200' cable wrecker a few big trees and 4 hours in very cold creek water we got it to the bank. The heater fan was still running even though all electric appeared to be off and by this time dash light came on and this is with the key off. Extensive drying and disassembled intake and battery. Charged battery, tried after several days to dry things out. I was unable to turn engine over with long breaker bar and pipe? because of belts to hydraulics?, On the starter end just clicks an dash light go out, swapped relays around to solve error codes, dry out fuses and box. taken water off the intake side, drained oil no water there and fuel looks uncontaminated. Any directions to go next would be appreciated.
