couple questions

[osenga 1]

got the k341 up and started today . sounds strong but . It is not charging it has the old (fin) style regulator I belive that it is bad .And I was wondering if The new style one will work? When i change the wires over do they go back one the same post since they both have 3 post do they just change over like that does anyone know And for my other question I was mowing with the 7114 today and I think the guy that turned around in my driveway with a trailer and it had a JD on it and I then a little bit past then mine is acting up now I am on all flat ground when I am turning either way my tractor looses speed and will almost come to a stop and all my fluids are up and the filter and all was just changed out on it and it is hydro any ideas
