zg 23 replaced voltage regulator

[damon.auto.tech7785]

Hello,

Have zg23 zero turn. Replace the voltage regulator and only have 12.5-12.7 voltage. Check ground and have good ground and tested the battery and have a good battery. Any other things to check to see why not charging. FYI, this is the second voltage regulator in a year that has been replaced.

Thanks

I am not an expert on these engines.
The charging system is a coil of wire under the flywheel which has embedded magnets.
The output from these coils will be alternating current. 25 volts approx.
The two output leads from the flywheel coil go into a rectifier/regulator.
This device cannot lower or increase the output of the charging system coils.
The reg/rect will convert the AC to DC and limit the voltage that can go to the battery. Any output in excess of battery needs is turned to heat usually by fins or aluminum body on the reg/rectifier. If the back of the reg/rect is aluminum it will need to have good clean contact to wherever it is mounted to dissipate the heat.
The following youtube video is a good description on the system and how to assess it.

In my limited experience, a corroded cable between the reg/reg and the battery was forcing the reg/rect to deal with an excessive amount of output that had to be turned into heat.
