Hey guys i have a question. I have a 48inch walk behind its model number is sw48-14ka. I took it to the shop today to get looked at and they gave me the stuff that was wrong. They said i need an ALTERNATOR, REGULATOR AND WIRING. Now i looked up all the parts and i cant find an alternator and regulator if anyone has any idea where i can find one id appreciate it. They gave me the quote of 550.00. Is that a good estimate or to expensive. Any help would be great!
