Motorcycle Repair: How to test a stator, style engine, stator


Question
Thanks for teh help Mike, but I am still lost.  The stator measures good as it is not shorted to ground, in fact it is a open circuit on both of them.  We are getting the higher voltage, 50 or so volts, at around 2000 rpm.  The higher the rpm the higher voltage.  The battery is just three weeks old and seems to take and hold a charge well.

Can the regulator be checked without the load/battery connected to it?  What is the next step, as everything looks good, but it is not charging?  Thanks again Rick

Hello and thanks for taking the time to help him if you decide to do so.  I am help a friend who has a S & S 124 cc Evolution style engine.  I know this is not a Harley, but a copy.  But my question is about the charging system which is made up of all Harley parts.  

The battery is not charging.  Thr battery is less than 3 weeks old, the voltage regulator is one day old(H style 32 amp, same as the original) all wires involved in charging are in good condition, including engine and frame to batter ground, nothing else looks to be a heavy drain to negate the charge to the battery.  The following measurements have been taken:  Voltage Regulator-diode check each (it has two) pin to ground .460 one way and open circuit reversing the meter leads.  Open circuit between both pins both directions.

Stator 5000 ohms across both pins, either pin to ground-open circuit, bike running puts out 13-50 volts AC.  The Voltage Regulator was replaced due to arcing which burnt one of the pins, likely due to a loose conection.  I installed bullet connector jumpers to make sure we are getting good contact stator to reuglator after the burnt pin and all is good as I am reading the stator voltage at the regulator.

Battery reads 13.08 after charging, 12.77 to 12.11 when running.  Lower and lower never increasing even when giving throttle.

So can you be of help?  Am I checking the components correctly, especially the stator?  Thanks you for your time and help.

Answer -
You never said if you checked the battery to make sure it is good, so test it first.
testing the stator. First check for ground with your OHM meter. From one pin on the stator to ground. Nest check the other pin. If you have a ground, or any OHMs, its bad.
the 13-50 Volts you are showing. At 2000 RPMs you should have the higher voltage. If not then its bad
Good luck and happy riding

Answer
Since you have changed the voltage regulator and the the battery is good and the wiring fine then it has to be the stator. I have seen stators test ok and then remove them to find that they are bad. Insulation off the wire and when the bike is running it is hitting the inner primary.
Good luck and happy riding
