Why my ATV battery wouldn’t charge – the rectifier

Link to rectifier: My battery would never stay charged. I suspected the charging system as opposed to a leak but only recently got a service manual from the library and after testing with a multimeter found it was the regulator/rectifier which was not doing it’s job. Although Honda wants $300 for a new one, I got a used unit off ebay for only $40 and it was easy to install. Now the charging system works like a champ. That’s called saving money folks.
