Massey Ferguson 5713S problem

[Joebloggs]

Evening all

Bought a s/h Massey Ferguson 5713S with less than 2k hrs on a week ago. Been great until yesterday when it went flat all of a sudden. So jumped started it and it ran fine.

Today It came up with an error and revs climbed. Locked all hydraulics and had a (!) and yellow tractor underneath it which I’m pretty sure is break fault. Parked tractor up and has gone fly again

any ideas before I get dealer involved?

What was the error that came up

No Error that stayed on it.
found that if it’s stop start a couple of times in a morning then the battery would go flat

been making sure I do enough work once started to keep it from going to flat on the battery but there’s something odd.
If the tractor is running daytime with nothing on the charge rate is about 13.8-14.2v
If the aircon is on at idle the engine hunts.
And last night the aircon and all the lights were on and the charge rate was down to 12.1v. And the lights would dim

alternator problem or something else?
