Regulator

Roughly one year ago I bought a used '02 Dyna Low Rider. The bike runs great but a few months ago using an ohm meter to test the stator, voltage regulator and battery I figured out the regulator was bad and replaced it and got a new battery. After that everything worked properly until now. So within a few months the voltage regulator has gone out again and I am trying to figure out if I just had bad luck with 2 regulators and install a third or if there is something wrong with my bike. I have some mechanical and electrical sense, so the next question is if there is something wrong with my bike causing the regulator to go out is it something I can check and fix or would it be better just to take it into the shop? I appreciate any help anyone could offer.

From:

Curious what symptoms caused you to suspect a bad regulator & what tests you did w/the ohm meter? One of the best tests is to use a test light from each regulator pin to ground, if the bulb lights up (at all) the reg is bad.

Many a regulator has been done in by a bad stator. What tests did you do on it? I'm sure you know that there should be 'around' 20-25 VAC per 1K RPM across the stator connectors. Resistance between stator connectors should be .2-.5 ohms. Also, the static test for a grounded stator may not be conclusive. A better test: with engine running use the test light from each stator connector to ground, if it lights up; bad stator.
