2018 2545 CL Starting issue

[Robert Cr]

I have a 2545 CL mechanical shuttle I washed the radiator and condenser the day after a hard day of mowing tractor was not hot. It was running perfectly before I washed with a garden hose (not pressure washer) Now it will not start with the ignition, it will not even turn over. It will however start and run if you short across the starter with a screwdriver. Checked the key switch it is working, 12 volts when the key is turned. I have checked the clutch safety it checks out with a multimeter and I even made a jumper wire to bypass to confirm. I pulled all the fuses they are good, I plugged and unplugged all the connectors under the dash and hood to check for bad connections. I have not found it the tractor has a shuttle safety or where it might be hiding. This is the second time this has happened after washing the radiator, the first time it went to the shop for service and they did not find any issue, when I got it back it was working as designed.
Has anyone had one of these tractors with a similar issue? Does anyone the starter wiring diagram for this tractor? Does it have a shuttle safety?
I can start it with a screwdriver and it works perfectly showing no codes or issues.
Signed tired of using a screwdriver on a new tractor.
I would take it back to the dealer but its like 6-8 week lead time they are very busy this time of the year with hay season. I mow my yard 7 acres with this tractor and can not be without that long. Any help is much appreciated.

It sounds like if you weight six or eight weeks to take it to the dealer it will cure itself. You obviously got water somewhere the tractor didn't want it. Try to figure where all water may have sprayed. If you can identify that component and dry it the tractor will probably go again. I don't know how you hosed out your radiator but the best approach is from the engine side forward.to clear the radiator - opposite to the direction of air flow.

Look up a tool callee the radiator genie. You should find a 2 wand system under that item. One wand does water the other does air. Start using the sir wand to do most of your cleaning if you have access to compressed air.
Also clean from the fan side out reversing the path of debris entering the radiator. Also try to cover any electrical components to prevent getting water on them as you use water.
Somewhere an electrical component is getting wet.
You may want to get service manuals if you do not have them.
Best of luck in tracking down your issue.

That is how I did it engine side out (to the front) it has been 4 or five weeks since the wash

Thank you! I will look into the radiator genie.
I still think it is a safety switch because the tractor will start and run if you jump the starter.
Mahindra is so bad about putting a huge amount of the electrical in the nose of the tractor.
I will get the service manuals for sure.
Thanks again
