When this first occurred at 1,085 hours, I did all the electrical diagnostic checks until I got to the Diode Block which failed. I got a new block and the tractor started right up. After two hours of run time it again would not crank. Diode Block failed the continuity tests so I took it back to the dealer and they replaced it with another new one. This time I checked the new block for continuity and if failed too. I installed it anyway but the tractor still would not start.

After much internet searching to no avail I gave up. After about two weeks I got time to dig into the checking again and decided to try the starter. Lo and behold it started fine and then worked ok a number of times during six hours total run time. Today, after using the tractor for two hours and stopping to change a blade, it once again would not crank. Help, please.

Thanks,
Larry

Don't remember the wiring set up on your tractor but I've been told that diodes will burn out from too high a current (short circuit) or too high a voltage (voltage regulator problems)
