Chronic dead battery

My scag wildcat is going through a battery a day, it'll mow fine for 15 or 20 yards then the starter just clicks. Its a 26hp Kawi, about 2000 hrs. Tested the stator and it's fine. Voltage regulator failed its resistance test, can't remember the numbers but it was way off. I replaced the voltage regulator and put a new battery on and it's still going dead. Any ideas? Is there a chance the pto clutch is drawing on the system, or the starter? Other than those 2 things I can't think of anything else in the system that would cause a problem other than maybe a bad ground? I'd definitely appreciate any help.

Check to see if your motor is grounded. I have had the same thing happened awhile back on a turf tiger at the regulator's ground.

I hate to sound like too much of a dummy, still learning the electrical stuff. How do I test to see if the motor is grounded?

When running how many volts is showing at the battery? Have you checked the fuses?

Use a jumper (cable). One end to engine other to battery -. Test output

Its a scag wildcat....replace both fuseholders...fixes 90 % of the charging problems on scags...
Use inline fuseholders from the autoparts store....

Just throwing this out there...
Check the connection between the charge wire and the regulator. If its loose at all (or dirty) it wont keep the battery charged. Its a little plug type thing. Have a look inside, get a little screw driver and carefully bend the metal connection thing to tighten it up on the regulator.

I have to do it at least once a week and keep checking the voltage going to the battery with a multimeter. Just the other day, I thought that plug was on tight enough, checked the battery at full revs and was only getting 12.3v to it. Tightened up that plug and it went up to 13.9v at full revs.
A new plug is on the "to do" list!

Thanks for all the help guys! While running the it was charging 13.7 ish to the battery. I have checked the fuses and they are ok, but replacing the holders is probably not a bad idea. I know one is pretty dirty. I gave all the connections around the regulator and stator a once over with compressed air and some dielectric grease. I do wonder why they don't use better connectors on the mowers though, I think weatherpack's would be way better. Maybe a project for next winter. I will let you know what I come up with. Thanks again for all the suggestions.

Problem ended up being a bad fuse holder in the charging system. Seems to be good now. Hope it stays that way.

Suggesting that to the manufacturer would only result in more headache and far more expensive mowers with little actual improvement.
