I have a Toro Z Master model 153-52 with 23 HP Kohler engine that quit re-charging the battery. Would like to buy the repair parts and fix the problem myself if it's not too complicated. Can anyone help???
Check the voltage from the alternator to the voltage rectifier, with the engine running at operating speed you should get around 35 - 40 volts AC (depends on engine rpm's) if not then the alternator may be bad, if this checks out then check the output voltage from the regulator it should be 13-14 volts dc. if not then rectifier/regulator is probably bad.
There are sometimes a fuse in the charging circuit, make sure it's good if there is one there.
