Battery light on JD 757

[DLCS]

Hey guys my battery charge light will not go out on my JD 757. Starts up and runs fine but light stays on. Dealer says its probably just the voltage regulator, I ordered a new regulator tonight. Has anyone here had the same problem? If so whatwas the cure.

Well, it wasn't the regulator. Any suggestions?

Hey Mike,
Just saw this in another thread. any chance this could be your problem?

If its a Kawi twin I have seen a lot of units Cub,Lesco viper/Ztwo(same H@ different dress) They mount the charge wire with a single connector on the voltage regulator and they tend to come loose, fall off or just vibrate on the connection and arch. It's so common that its the first place I look when someone tells me their mower is not charging the battery.

What engine is on this unit ? Have you put a multimeter across the battery post with engine running at wide open throttle to see if it is charging or not ?

25hp horizontal Kawasaki. Yes we used a ohm meter and its not charging. Wide open throtal, we only get 12 volts. Funny thing is that it happened the day after I washed it. I first thought maybe i got something wet but I don't know now.

I've checked all the connections and wires. The first thing I thought was maybe a wire was loose.:confused:

Mike, Since you have a multimeter perform the test below. Since you have a new regulator on there this test will tell you if the stator is bad or you have a unit wire harness problem.

Thanks, nice instructions.:) I'll test it out tomorrow and get back to you.

Rob,


Everything tests out out ok. I even had my dealer check also to be sure. Kinda has us puzzled on why the light is still on. Mechanic said to run it cause everything is fine. He thought maybe there is a diode somewhere that has gone bad and is keeping the light on but its not shown on the diagrams. I ran it all day Saturday and no problems, going to try it tomorrow but I'm sure it will be fine. Just is strange.:confused:

have you checked your fuses?

Only one fuse and that was the first thing we checked.:confused:

Just off hand it seems like the regulator - but I know you've changed that. Do you have a wiring diagram showing the charge light curcuit?
Are all the connections good on the ignition switch?
Do you get at least 28 volts AC across the stator leads while running full throttle?

Turned out to be the stator. Oh well only cost me $48.:)

I was wondering what you ever found out....Glad to hear you got it solved....Thanks for posting.

Seee Ya

Thanks for the help Rob and all the other posters.:)

DLCS,
How did you determine that the stator was bad?
