Question
QUESTION: i have replaced the battery with a new one, but the battery light still comes on when i engage the pto switch.
how can i find the answer to this problem ?

ANSWER: Have you measured the battery voltage when the engine is running full throttle, blades off and measured the voltage when the blades are turned on?

The charging system needs to produce sufficient voltage when the blades are turned on to charge the battery and run the blades.

Let me know what the voltage readings are.

QUESTION: engine running full speed blades off 15 volts dc
engine running full speed blades on  15 volts dc

i hooked the ohms meter to the battery and mowed little more than a 1\4
acre of deep grass with the blade height at setting 8 and the battery light stayed on all the time the blades were running,
setting 8 is 3 sets under max height.
I really appreciate your help.

Answer
15 volts DC is border line high.  I have a voltmeter on my motorcycle and in 2 cases the light came on and the meter was reading just over 15 volts.  Shut it off, restarted and the meter read 14.7 and the light went out.

Does the charging system have a regulator?

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
