So battery won't charge on my face .....
.... I've never had any real issues with it before any help would be great
Any help? Ok:
"Battery won't charge on my Ferris. It's a new battery that is dead so I put it on the charger on it. It holds a charge and will start the lawn mower once or maybe twice.
I bought a multimeter and I tested the voltage at the battery and I'm getting like 13.5 - 14.5 volts there, so it's taking a charge, but was not staying charged. I don't know what possibly to look at next.
I've had a previous Ferris mower that did the same thing and it turned out it was the magnets on the coil(?) (flywheel?). Magneto (?) had been broken or reversed somehow and so it just never charged and it always had problems. There's only 340 hours on this machine and I've never had any real issues with it before. Any help would be great."

Having 13.5V to 14.5V when running or charging shows that your charging system is working. When off, the battery should be about 12.6 (2.1 volts per cell).
It sounds like you have something draining the battery when turned off. You might want to google "how to test battery for a parasitic load or parasitic drain".
One tests you can do is disconnect the positive terminal and place a little light tester between the battery post and connector you disconnected. If it lights, it means you are seeing a current flowing, draining your battery through a path that shouldn't exist when it's turned off.
Step 2, of finding what's doing it is harder. Leaking (key?) switches are likely suspects.
p.s. You can also do the same test your multi-tester.
