318 charging system

Garry My 318 charging light glows most of the time when I am mowing. Any ideas?

Thanks

Dave Garry - The charging system is not delivering enough voltage and has dropped below 12.3 volts. The PTO clutch could draw the system down if the field coil is weak. The voltage regulator could be failing, or the stator could be shorted or weak. You could even have a weak or dead cell in the battery.

First thing I would pull the battery and have it load tested for a weak or dead cell. If that checks, then pull the middle wire from the voltage regulator and with the tractor running at full throttle, check the DC voltage using the engine block for your ground point. If the voltage is not at least 13.5 volts DC, either the regulator or the stator may be bad. If you are getting the voltage, then I'd look to the field coil on the PTO clutch. Check your voltage after having the battery tested and post back. - Dave

Tom I had the same problem with mine. I replaced the three wire connecter because it was corroded and it solved my problem.
Wally Wilkerson I am experiancing the same problem. The battery also loses its charge after running for awhile. Just replaced the battery, so I don't think that's the problem. Would I go through the same diagnostic process?
