It is true, it could be the stator, alternator, which is located under the flywheel, but it could also be the voltage regulator

Charging system failure low voltage


Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12 volts or better after charging.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor. Good luck

My riding lawn mower turns over but not fast enough to fire cant figure out whats wrong please help


I assume an electric start. Slow cranking could be low battery voltage or capacity. Check battery voltage with a digital volt meter. It should be 12.6 volts. (Unless it is a 6 volt battery which should read 6.3V when charged.) Under 11 volts it is dead.

To check capacity see how much the battery voltage drops while cranking. It shouldn't drop more than a volt.

Riding mower not charging battery


Sounds like a voltage regulator or diode. Do you have a multimeter? If so attach leads of multimeter to batt terminals, red lead to pos and black lead to neg. Start unit and observe meter readings. Then move throttle to high and continue to observe. You should have 12-14 volts on meter reading. If not your regulator or diode is bad. Message me back after doing this and I can continue to help you. Also, make, model and serial number of engine would help too. Good luck!

Check the brown wire feeding your voltage regulator,its between batt and steering wheel behind left side of frame.LX100 series machines had a problem with brown wire not fully contacting terminal in regulator.You will know you had bad contact if plastic is discolored.

Craftsman lawn tractor model new battery drains quickly...


it could be the stator in the engine check the voltage with the volt meter when its running if its low check connections on battery & voltage if its below 12.5 volts then its the stator but the only thing is the engine should run with-out the battery so there is something else going on there is a fuse in the electrical system if theres a short that fuse will blow & engine will stall

Where is the fuse for Craftsman 17.5 HP 42 Riding Mower


I'm not sure the solenoid/relay would even energize at 10 volts (so you may not hear the clidking).

The battery is essentially dead at 10 volts -- try charging again for 4 hours or so, and then measure the voltage.

If it's not up near 12 volts, you have a dead cell and need a new battery.

Check the seat switch for the running problem. Disconnect the switch and jump the harness with a piece of wire, and see if the tractor stays running. If so, then the switch is bad. As for the charging problem. Test the voltage regulator. Start the tractor and put a volt meter across the battery. Red to red and black to black. Run the RPM to full throttle. You should have a reading of 14 to 14.5 volts. If not, the regulator is bad. Hope this helps.
