I never have liked the idea of the alternator in oil. had on fail on a Suzuki GS1000 years ago at 30k miles. my 87 kawasaki concours had a dry alternator, still working at 90k miles when sold.

I agree. Electrical components in any kind of fluid just seems like you're setting yourself up for failure.

Transformers have had oil in them for years. Used as a cooling agent. Those HUGE transformers you see hanging on telephone poles? Yep, oil filled.
!!! I was like yeah !!! :P so far so good, taking for another ride Sunday as tomorrow will be windy and Windsurfing is also very fun !!! Brembos YEAH !!!!! I guess I got stat looking for them
Here some pics of the bob

Bike had to go back to the stelership after replacing only the voltage regulator.. After telling them since first visit that the issue was the stator and also a bad regulator.. HD wanted to charge me U$1000 for the work including parts.. What a rip off, got the stator and a gasket for the primary just in case. Replaced the stator within 2 hours. bike now running like a champ..

Ok so I got a multimeter and have been doing some checking before I go digging into the primary. I started by checking resistance between the 3 terminals of the stator. I got a consistent reading around 0.6 for all terminals. One thing that confused me a little was when I touched the two leads together on the meter it should have a resistance of basically 0.0, right? I know the wire has some resistance but it was reading 0.3. So is 0.3 really my 0.0 so my terminal-to-terminal reading is actually 0.3 less then what the output says?
I checked terminal to ground and that test passed.
I check battery voltage and I was at about 13 DCV with the key off. When I started it up and raised the RPM's to around 2000-3000 the voltage stayed the same. From what I've read it should raise as you rev the motor due to the charging system. So does that mean my regulator is bad? All the tests I've found for the regulator don't seem to apply to the connector type that Harley uses. Also, my multimeter doesn't have a diode setting so I couldn't test is anyways.
Is there another way to test regulator being bad as opposed to stator? If I can avoid opening up the primary I'd like to. I also don't want to buy a $160 part and find out that wasn't the issue or possibly fry the new regulator due to a still faulty stator.
Any thoughts? Thanks.

hey man! I have the exact same resistance on my bike. Although its a 2016 FXDB, passes ground test and output test. Replaced regulator and and battery.. fixed my charging issue. Wondering if the stator is really good...
reading 14.4 at idle and around 14.54/14.6 at 2000rpm
