continuation of the charging system irregularity
Is there a way to test the regulator output?
I put another used regulator on the bike but it behaves the same as the old one. Is it a bum regulator or something else? Ir is not regulating the volts to around the preferred 14 but it sneaks slowly up to between 16 or 17. Need help here. Going to put my old battery on it for now so as not to cook the fairly new one.

Possibly a grounding problem... Insure the regulator mounting bracket is tight to the frame... Also insure the connections on the solinoid are clean... Follow the battery ground wire tothe frame and clean that area too...

All this does not rule out the possibility of both regulators being bad...

Removed and replaced the main battery ground cable and ensured the contact areas were sanded and clean. Checked connectors on solenoid and connectors were tight and very clean. Checked out regulator mounting for proper grounding and everything was cleaned and tight. Also attached additional ground source to regulator body ( booster cable to engine ground) and still not difference. Idles around 13.8 to 14.2 but increased revs puts it up to around 16.8. I am running out of options other than try another regulator.
I have another cheap used regulator on the way to try next.

What model bike is this on.??? The SEI and LTD used a higher output charging system... Are you sure you are getting the correct regulator for your bike.???

Jim~ I've posted about this on your previous inquiry. The regulator does not find it's ground through the body of the regulator to the frame.
There are two green wires that come from the regulator. They go directly to the main harness ground just below the regulator bracket. These wires are the grounds for the regulator. The regulator does not even need to be mounted to operate.
If you have 14+ volts supplied to the regulator (black wire), and the two ground wires (green) are clean and tight, the regulator is faulty.
You are making too much work for yourself.
Three yellows in (stator leads)
Two red/whites out (voltage back to the battery/solenoid)
One black (sensing voltage)
Two greens (ground)

The model number on each regulator is the same as the one that came off of the bike.
I will check the green wires to see where they go to and try and track the problem. I have checked the red wires and black and I know the yellows are producing ample power.The best way I guess is spend the time and remove the faux tank and follow the wiring diagrams in the service manuals.
Thanks glhonda.

The last thing I need to track down regarding the regulator wiring is where do the green wires connect to the ground ( frame)? If anyone has traced the wiring or perhaps removed a wiring harness, where is that connection? Would save me a lot of trouble in tracking that on the bike. I also thought of jumpering the green wires on the regulator to a new ground to see if the regulator starts behaving better. Lately when I first start driving it it registers about 16 to 18 volts and after a while it mysteriously drops back down all of a sudden to 14. and stays that way. So I really think this regulator I got is a bit flaky. Still waiting for another used regulator to try out to verify the findings.
Cheers.

if the regulator is still attched to the circuit my suggestion is to completely hardwire around that,it is a source of problems just like the stator wire connector by the battery

in the process tap off the ground wires to the frame also,a bad ground could be your source of part of the problem too

on mine i combined the reds togeter using 10 ga to the reg and the same way with the greens along with adding a 12 ga wire to ground near the reg mount

voltage ended up increasing by .3 volts and was rock steady after that

cant hurt if your thinking the reg is bad to start with

Thanks for the picture. Rather than go to the trouble of removing the trunk, seat and faux tank, I soldered in a new wire to the green wires on the regulator and to a new frame ground. Still the volts are up at 16 to 18 when on the bike for a short while. Then it sometimes it will jump down to the norrmal 14.1 and stay there the rest of the ride. Will now wait for another regulator which is on it's way. Unfortunately (fortunately)I am off to England this Sunday for a little over two weeks so it may be a while before I can report back on the situation.
Thanks Wingers for all the great help.

since you've added a ground but still having problems i would almost have a say that i think your problem is in the regulator connectors especially if you still have the same problem when u get the new regulator

good luck and enjoy your trip
