Repairs X300 PTO Kills Engine HELP!

[rangid]

I think I read that post and gave it some thought; and considered changing the battery.

May have forgotten to mention the seat switch but it is good.
I guess it's possible that the ECU has to have a fully charged battery to put 12 volts through the blue (clutch) wire but the battery is fully charged and there's no problem with running the deck when jumped.

But since I could use a battery on my Snapper RER anyway and the one on the X300 will be plenty for the 16hp Vangard, I will buy a battery for the x300 and recycle the old one to the Snapper.
Not sure when I'm going to do this though; maybe over the weekend.

Thanks for reminding me of that post because I had already put it out of my mind.

I came to the conclusion that the ECU was only feeding 6 volts to the pto with a fully charged battery and all safety switches working as they should so it must be the bad part.

My solution was to jump the gray wire from the pto to the blue wire at the fuse block enabling me to use the pto switch to run the deck instead of adding a toggle somewhere for a direct jump to the battery.

I cut the blue wire and the gray wire adding connectors in case I ever want to buy a new ECU. Just reconnect the blue back to blue and the gray back to gray.

By cutting the gray wire from the pto switch and jumping directly to the blue wire I also installed an inline 5 amp fuse to keep the circuit protected.
The gray wire gets 12 volts from the yellow wire when the pto switch is put on.

The key here is that you also have to disconnect the grounding wire to the coils in the area where the white wire feeding 12 volts to the carb solenoid.
When you turn the key to off it no longer grounds the coils, but it kills voltage to the carb which kills the engine after about one second. You can also kill the engine by chocking it if you need a second method.

I also don't have to worry about pulling up on the pto switch to cut in reverse. So it's a win-win for me.

Thanks for everyone's interest.

Final update on this issue;

I didn't like that I lost my hour counter and the fact that it took 2 or 3 seconds for the motor to cut off when I turn the key to shut down after.

So I've been watching ebay for a new Interlock module at a good price and eventually last week one popped up for less than $40 free shipping New in box.

I just came in today so I put the wiring back the way it belongs including the coil grounding wire; installed the new module and presto chango...works like it's suppose to.

I will try using it the mower with the RIO factory setting to kill mower when reversing if the PTO handle isn't pulled up and see if I can get used to it.

If not I will bypass the reverse mode. But it's nice to have the electrics the way was intended from the factory.

That's all folks;
