Nothing I did was overly difficult. The most time consuming part was researching the charging issue and what to do about it. It seemed everything I read... this tratcor was doing, all the way from lack of charging to the soliniod on the starter not engaging. Thats when I decided to replace the whole system. Have a very positive engagement in turning the key now. not a soft slop of a twist.
The most difficult part was removing the original drive shaft... not an easy process.
I'm an ebay junkie.... Im sorry, please dont judge me
