Charging system question...Craftsman LT1000


The battery doesn't seem to be holding a charge that well. The amp gauge reads at a negative discharge ( at idle ) and smack dab at 12 o'clock at full run speed. I back probed the electrical connector and am getting 30 VAC at full run speed. However, when connecting the probes of a voltmeter to the battery and letting the engine run at full run speed...DC voltage climbs to about 12.8 volts and that's it.

Shouldn't I be receiving a voltage reading of 14 volts or a bit higher? Also, I do not see a voltage regulator anywhere on the engine. Are some mowers not equipped with a voltage regulator, or am I simply missing where it is housed?

I appreciate your thoughts...thank you!

i realize this is over a year old, but yes, you should read about 13 or 14 volts immediately after starting...when the battery needs some recharge.

I'm posting this mostly so that readers may learn YouTube is a godd source for many common issues.

To identify your voltage regulator, see here:

To find out out to test it, enter your question in Youtube.
