86 1200 sei dies while riding

Postby wing86new1 » Fri Mar 21, 2014 7:24 am



Here is a issue, just want your guys thought on this. got the 86 out yesterday for a ride - voltage meter steady at 14.4 after riding for 5 minutes flipped on the running lights (these lights have no short on them just acquired the bike in the fall, the previous owner was convinced there was a bad stator) voltage started dropping slowly to 12.5 in about 5 minutes, and leveled off there. then the fuel light appeared and the bike dies at 55 mph, glided off the road shut it off, turned off all accessories started back up and drove home with no failures (charging circuit back up to 13.9 )

the 3 yellow wires are soldered good, I did find in the fall some repairing that had happened to the regulator (bad repair) I soldered all these connections, when i measured from battery ground to the 3 yellow wires still hooked to the system, i got about 7 volts on each leg (still charging a low battery).

so i am thinking a bad regulator is the issue, i have ordered one, do you guys think this is the situation? the only other thing would be bad diode pack but they just fail to my knowledge.

Has been my experience that the stator is either working or it's a anchor weight. The regulator rectifier can be finicky and even when testing good still not work right. I some times think the heat really gets to them. Don't forget that a battery starting to go south can also cause headaches.... Do let us know what you find out..
Enjoy the ride. They are all good, just some better than others.

The r?r module normally runs very hot...My 84 would reach 165* in just 10 minutes.
I'd also quit using the "running lights"..by your description,when they were turned on,the voltage began to drop off...this indicated that the "lights"are drawing more power than the system can provide .A small drop,say 2 tenths would be OK but to draw the battery down to 12.5 volts...that's a heavy load....
You might get away with maybe a 60 watt drain on the bike while it's above 2500 rpm but throw a couple of 55 watt driving lights on it and I will guarantee the battery will be carrying the load..The charging system just wont do it.

The 7 volts you measured.....Don't even go there...It's a erroneous number.There are specific tests for the stator coils in resistance and AC voltage measurements...
Generally speaking R/R modules either work or not....99% of failures are in the connections to it.
Inspect the R/R plug for ANY corrosion...The 3 yellow wires are there too,just like by the battery...
Have a read in this post...look at the pictures of my plug...It charged but not very well before I did this...viewtopic.php?f=5&t=12522

Limit your accessories....Keep the total accessory load as low as possible...preferably below 50 watt.

I was wondering about the load that it was being presented with, what is installed is lights under the hard bags, wing bar in the back, ring of fire in the front, triangle front light, and a eagle that lights up in the front, also has 2 "christmas trees" in the back and 2 35 watt halogens in the front- i did not have the halogens on. i have found in his records that this is the 4th regulator that he has had on the bike i almost bet he was running all these items at once. I can do a separate wattage measurement for the other lights with a meter tonight. I will post my findings

as far as hot is concerned was just a figure of speech, i was trying to see if i could get it to fail

well i think i found the root of all the issues. too many lights. i dont know what the other owner was thinking but it draws 8 amps :o withought the halogens on. so im installing the new regulator when it arrives since the other one has been stressed. and will remove all the extra lighting unless i power those with some lithium ion battery

will post back when regulator is in and i get a sucesful trip

All the lights are pretty but the system will never have a extra 165 watts to spare.

one must remember that these stators put out 300 watts at 5500 rpm take a headlight at 55 watts couple of marker lights at10 watts each dash lights and efi system and at 3500 on a highway you may be maxed out without even turning other lights on. Stu in wing world did an excellent article on electricity aimed at classic wings taught me a lot. the 86 sei does require the right voltages to operate correctly. I did kill my 77 stator with 2/ 55 watt driving lights and not paying attention to the yellow wires. My 82 1100 and 86 sei are still stock with no extra lights.
do the tests for the stator and if good watch your electric load. Good Luck

well went ahead and removed all aftermarket lights, and installed a new voltage regulator. seems that the old regulator must of been burned out partially, within a couple of minutes the old regulator would get hot to the touch, the new one kept cool even after 15 minutes and charging is way better, if i just touch the throttle now it jumps to 14.4 volts, when idling at 1050 rpm for 15 minutes the voltage stays at 12.9v and just a little open up on the throttle brings it back to 14.4v in about 10 seconds. the real test should be this weekend for a ride weather permitting (its snowing now :oops: )

Keep in mind that the rectifier/regulator module is a "shunt" device...As the voltage reaches 14.4 volts on the black sense wire,the regulator actually shunts(shorts) one leg of the stator to ground to keep the output of the module stable...
This shunting does dissipate in the form of heat...It wouldn't be uncommon to see over 165* in normal operation.

Well got some riding in and was ok for about a hour, then it showed up the stator is bad- almost did not get home. so im going to pull and change it. but I have a question for everyone. I see that there is some stators on ebay claiming that these models have more output 20% more than factory like this one, http://www.ebay.com/itm/150986747409?_t ... EBIDX%3AIT have any of you tried items like these they cost pretty much the same, I was wondering about failure rate, I know this guy says a year warranty but I dont want to have to pull the motor again..

Try this link same thing no ebay bull. some may have smaller wire windings than others and perform not as well I have only bought 1 if I remember it came from a catalog in a bike shop. Bike bandit shows ricks as well in after market parts good luck

here is a stator on ricks motorsports, http://www.saber-cycle.com/store/product628.html should I be looking at this instead ?

I have bought 2 of the Rick's stators. Here is their web page.
http://ricksmotorsportelectrics.com/par ... RpdGlvbg==
Mine were for the 86-A. Just stay away from anything made in China..... Junk....
Also when you install that new stator put a little dab of sealant where the plug and wires go thru the case. Making sure those wires stay on the back side and the plug not turning. My last one got twisted and moved the wires on the inside causing rubbing, cutting and failure.... Have fun I've done it 3 times........ Did I mention I love stator's...... :x
Enjoy the ride. They are all good, just some better than others.

thanks for the advice how long could i expect a stator from ricks motorsports to last I have removed all aftermarket lighting. also what about switching to led's for the factory turn signals and stop lamps?

That stator should last a long time. Just make sure it gets hard wired. Leds can always be used, they use less watts. Wingman has some good stuff on led's. The stator lives in a hostile environment. Change oil often as I think any acids eat away at the coating causing early failure. I change every 3 to 4k. Honda says 8k, not......
Don't get me wrong I love my 86 and it has taken me a lot of miles. Don't know about the SDI but install a volt gauge to keep an eye on things.
Enjoy the ride. They are all good, just some better than others.
