I went with a new regulator for the time being, but I will be upgrading to a 32amp 2-pin system when $$ allows.
problem is, the new regulator isn’t making a difference.
-battery is brand new
-stator is putting out 50 ac volts at 2K rpm
-grounding of regulator seems good, I even ground off extra mount paint and ran a supplementary ground wire to be sure.
-Regulator is wired directly to Positive battery terminal
Battery is around 12.8v prior to starting, and drops to around 12.1v once running.
so, new battery, new regulator, juice coming from stator, and grounding seems solid. What else could be happening?
Thanks

What you don't want to hear, stator's going. Most likely an intermittent grounding situation manifesting when the bikes running and vibrations present pull it apart you'll see it usually a couple of the wires going to the pins the insulation is cracking off, I cooked 2 of the 4 pin before I got tired of dicking with them.

12.8 is Normal... and 12.1 running is normal if no charge is applied... depending on "load"..
What you need is a 2 pin Stator and Regulator... both... I don't personally need a 32 amp, as I don't even run with the lights on... unless dark of course..
As I said earlier... I refuse to fool with that 4 pin setup another second.... Besides I am stuck on AGM batteries, and that 4 Pin will Not charge them even close to Properly... the old 2 Pin barely keeps them where they need to be...the 32A setup??? yer AGM Battery will thank you......

But you are running a 2 pin regulator on a 4 pin setup???? Hope no. and you replaced with a 4 pin... from where???

As I said... I would have given up long ago...what you are describing is a ... Bad Regulator...
Unless that Battery is ****!!!!
Note... "New" means Nothing on this "stuff"..

says for Big Twin 70-75.
i know there is no reliable test for regulators, but for what it’s worth I poked where the power wire came out to the ring terminal at the end, and got about 1.2ohm resistance. I thought maybe there was a short in the wire preventing it from supplying juice to the battery.
Speaking of battery, I am running an agm style. It is also Drag Specialties, High Performance 310 cca for shovelhead battery tray.
