F525 Battery Overcharging

[bruce_tipton]

I have a JD F525 front deck mower that is running fine except that the battery appears to be overcharging. Electrolyte is coming out of the battery fill caps after I run for a while. Also, in two or three mowings the electrolyte level drops below the plates in the battery. Could this be the voltage regulator. I checked the voltage while the mower is running an it is at 14.5 volts. Any ideas??

Thanks,

Bruce

14.5 VDC is a little high but nothing to worry about. 13.8VDC is the standard for charging a 12 volt lead-acid battery. A high reading is not uncommom just after start up. It takes about 5-10 minutes for the battery to recover from starting the engine. Start the engine set throttle at FULL and wait 10 minutes so so then take a reading at full throttle. Can you mount the meter (duct tape?) and do some mowing and see what happens. It may be something that does not happen right away. Maybe it acts up only after it has been ran a while(gets hot). Good luck
