Voltage Regulator Keeps Going Out

I have a Briggs Vanguard model 303447-1319-E1 (5000+ hours) in a Toro Twister utility vehicle. Whenever I run a sprayer for a couple of hours it burns out the voltage regulator.
The sprayer has a 12v 11 amp pump. Is there a way to prevent this or can I upgrade the alternator?
 
Looks like the largest regulator they used was 10 amp which mean you are keeping the output pegged at max and will overheat the regulator and cook it. Would need to come up with a battery to power the sprayer that isn't connected to the engine charging system.
 
Hmm, the IPL shows a 10-16 amp , but only a max of 10 amp as far as the regulators go, but i did find A 10-16 amp, 845907 1633358786079.png

Actually the 10 and 16 use the same stator and regulator. Needs to change the flywheel to the one for 16 amp. But if there is anything else drawing current along with the pump it would still be operating at the upper limits of the regulator
 
Keep a spare battery, charged up in your garage to use for the sprayer and such things. Without a lot of work and expense, you are going to keep burning them up.
