Battery issue - 03 Tiger Cub - 23hp Kawasaki

So here it what I have found. Running wide open the battery is 12.6. The regulator is left lead ( stator) -20.6, center ( stator) -.25, Right lead -.25. Unhooked the power wire back to battery and the battery didn't change. With the blades on it still close to the same. So here's anther kicker to it, I was mowing this week and it died as it always does after a few hours, I swapped out the battery and continued mowing. When I was done mowing check the readings with that battery and the same readings, but the battery I took out when it quit still red 12.4 volts. So is it killing the amps and there is not enough to run. I've to the shop numerous times and it's the same thing, keep checking this and that. They told me if the battery didn't drop when I unhooked the power from the regulator it is something one the motor, but now with that battery still showing 12.4 I'm not sure what to do.
 
skooter, People keep answering you because you are trying. You are a victim of a gremlin which all tinkerers experience AND which has caused tinkerers to shotgun parts purchases out of frustration. I reread this thread. You still have not done the simple current drain check (key off)?? You have not mentioned using a battery hydrometer . They are only $3 and will give you an extra piece of information about your battery condition (caps must unscrew for access to electrolyte fluid). It may be time to start unbundling and cleaning all the wiring for a visual inspection. Look for worn insulation, shiny spots, loose connectors. Crud that can drain voltage to ground, Battery must not have corrosion on top, Battery hold downs must not be corroded. I make mine out of plastic. Things move around under vibration and heat. Things open up also. At this point shift your suspicions to "passive " elements like contacts and insulation. Some one suggested diodes. Your DMV can check them with power off. You may need to pull info down so you can recognize them. Remember many shop techs also have major difficuly with gremiins.
 
So I did some more checking. I found a white wire in the harness that in the book says it goes to the magneto, it is pulling 38 volts. So is it pulling more than the stator can keep up and that's why the regulator is showing -25? This may be a dumb question but is a magneto a coil?
 
scooter94,
Yesterday was the 5th month since your original post and the 5th page on this thread!
You need to get your machine to a Scag qualified servicing dealer and get this machine properly repaired!!!!!
It is time to fish or cut bait!!!
 
Re: Battery issue - 03 Tiger Cub - 23hp Kawasaki. FIXED!

So I figured it out. Pretty simple, it was the fuse. It looked good but I never tested it until today. So I wasted the money on the key but the stator I'm saying was previtive because of the oil on it from the leak I think it was only a matter of time before our cooked. So, I do hope this may help someone else as I have learned alot. Thanks everyone

So I have been having a few issues this summer. I believe I have a coil going bad. It looses power and comes back. When it is running normal I took the right spark plug cap off and it was doing the exactly the same thing. That's why I think that. Any chance that could be causing my battery to drain? I had it go dead on me so I bought a new one. ( It was pretty old anyways ). Something is still draining the battery. I can mow one yard go to the next and crank it and turn over a few times then nothing. I can jump it and it start up. Any ideas would be greatly appreciated.

I have the same problem. same mower. I bought a new battery last month,mowed like four times and now the battery has diminished to not starting the mower. I can jump it or just let it stand hooked to 12 volt battery,.It will run and mow fine until I shut it off.
