    I just installed a new flywheel and stator on my Kohler cv25. When I start it the light stays on telling me its not charging.

    The magnets fell out of my other flywheel. So I got a good used flywheel and a new stater off ebay. I installed them and now the light is always on.

    I did however removere what looks like a jumperwire and can not remember exactialy where it goes back. I read somewhere that this jumper wire is very important. Can someone please help me????

    I have done alot to this motor, new exhaust, gaskets here and there, new seat, new hood, bumper, lights. All bought off ebay for 10 cents to the dollar. I want to get this thing going.

    Maybe this is the jumper you are talking about

    Thats it, and that is where I put it backat, but then took it back off thinking it didnt go there. I will put it back on and try it.

    If the light stays on what is my next step???

    Hook up my meter somewhere??

    You will most likely find re-hooking that ground wire will fix your problem.

    This type of rectifier/regulator is a reference voltage sensing type. That means it has to "see" the battery before it will switch on. To see the battery it has to receive at least 4 to 6 volts. checked see that your getting battery voltage at the middle terminal on the rectifier/regulator with all the wires plugged up and the key in the run position (engine does not need to be running as all as the key in RUN). If it does not get the reference voltage it will never put out.

    Hey I installed that jumper and its charging. Atleast the light went out!!

    Since I bought it over a year ago it never did charge. Finally the rest of the magnets came off the flywheel. When I took it off it looks like 2 of them had been gone.

    Anyone have a parts diagram of a Scotts 2554. I need the hinge mechanism/bracket that holds the front of the hood.
    I cant find anything about Scotts online.

    Once again thanks for the help. I appreciate it.

    Well i tried the mower but when I engage the blades the charging light comes back on.

    Is it going to ground you think?? I hope the electric blade servo/ whatever its called. Is not bad!!

    Any advice?

    Have you put a multimeter on the battery and checked the charging system out-put ? How old is this battery and how many times has it been ran down and re-charged ? When you engaged the blades did you give it full throttle to see if the light went out ?

    I know, A lot of questions but the more info. the better, What's the full model number (under the seat) ?

    The PTO clutch could be worn and drawing too many amps causing the light to come on, That's why I would like the full model number off the unit.
