John Deere 777 mower electrical question

[mowboy]

Mower starts and runs for 20 minutes then blades shutdown and then motor shuts off. Will immediately start with jump of battery. Battery is new and in good condition. I saw an old post that said they had found this to be a bad relay. There are 6 40a relays near the ignition. Anybody know which one would cause this problem. Is it a voltage reg problem?

Mowboy,

Good to have started a new post. I would want to get away from the MyJoBota.

Her is an idea, buy one of those relays at you local auto store. Take one of the relays with you when you go to the auto shop.

Now with a new relay in hand, replace each one, one at a time. See if that fixes it.

Hopefully that fixed it. He didn't come back either. :confused3:

:wrench:

Yeah, it would be good if he would have let us know what the outcome was.
