I have a CV25s-69518 on a Bob-Cat ZT21x that was purchased used about 8 years ago. It is used just for my property and I am not sure what the use was before that.
I have had the heads rebuilt 3 years ago and up until now haven't really had any huge issues. This year, I had issues with the solenoid on the carb. The unit came with an extra carb as the previous owner had bought another for it. I rebuilt the extra carb I had this year an put it on the mower which settled several issues all at once and then it quit charging.. I also had some of the wiring come loose from the plug that goes from the rest of the unit and to the motor. I cut those loose from the plug and wired them back using bullet connectors I also popped the shroud and saw that some of those wires had come loose from their connectors so I replaced the connectors. I went through all of the wiring and didn't see any cracked or burnt wiring or any that had the insulation scraped off. I thought this would settle what I thought was a starter issue and in a way it did since 1 of the wires that backed out of the terminal was the ignition wire. After refreshing everything, the mower still didn't want to start so I replaced the 4 year old under amped battery I had with a 350CCA Duracell. That's when it dawned on me that it was a charging issue. I checked the charge at the battery with the motor on and it read 11.8v. I checked the 2 outer posts on the rectifier and it was steady at 33v AC...checked the middle post and there was no voltage at all so I figured it to be a bad rectifier so I replaced it and am still not getting any voltage through the middle post.
I may not have understood how to check it. The way I did it was set the multimeter to voltage DC and then touch the red lead to the middle post and the black lead to a ground. Is it possible I got a bad rectifier out of the box or is there something else I should check? The new rectifier was a kohler OEM part # 41-403-10-S. I have read through most of the charging issue posts but most were resolved by replacing the stator which I assume is working at 33vAC or the rectifier which I did
