voltage regulator

Postby brianaber » Sun Mar 15, 2015 1:09 pm



84 gl1200 ltd digital gauges !!
over charging have come to the conclusion that its the voltage regulator , seems to be a lot of different opinion's :roll: on what regulator to buy
any recommendations??
thanks

WingAdmin, the expert that he is, has designed, built, and sells a 7volt regulator just for GW that use this component. Check out http://goldwingdocs.com/Store/Goldwing-7-Volt-Regulator.asp

And see if that fixes your problem. There is a write up that goes with it.

Overcharging may not be related to the regulator.
With a digital volt meter,measure the voltage between the positive battery post and the small black/white wire at the regulator.It should be below 0.50 volts DC.If its above one volt,the output of the regulator will increase.
If its above 0.60 volts,a relay can be wired into the circuit to cure the problem.
And yes,I'm taking about tenths of a volt.

There is a detailed 3-part test for the stator , described here, about 9 posts down :

viewtopic.php?t=11343

Summary of this 3 part test is
- 3 yellows, A, B, C and test each for short to ground
- in pairs , across each leg. A to B, B to C, then C to A about 3 ohms resistance
- Start bike, on AC Voltmeter check leg A to B. then B to C. then A to C.
and each should give 50 to 75 VAC, depending on RPM of engine


The Honda manual has a similar 4 part test for the Reg/rect :
Ohmmeter on yellow to green - 0 resistance , reverse it to show infinite resistance
Ohmmeter on Red to yellow : 0 resistance , and reverse , get infinite resistance

SO ....................
Unless you've done all 7 tests, I would not replace anything .
Most flaws are yellow wire connection, or Reg/rect connections, or ground connections.
---------------------------------------

But if you have either component fail its respective test, the " best " reg/rect are probably those at Ricks Electric.

Much higher rated than most e-bay replacements .

They also make pretty good Stators.

Good Luck !!

.... and an 8th and final test, after its all re-assembled and running :

Start it up and slowly increase the RPM ...
-the voltage on the battery terminals should level out at around 14 to 15 volts DC, and NOT increase beyond that.

..... if it does not , and ALL the connections are good ..... then its time to replace the rect/reg

as they say in ITALIAN one million thanks to all of you ;)
flowed VIRGIL'S soldering tips ,...... started up top 13.8 volts , rode it home 23 k's ,once charging went up to 14.1,

what should max charging be ??

thanks again

FORGOT TO ASK , I READ SOME WHERE THAT THE VOLTAGE REGULATOR THATS AVAILABLE THROUGH THE GOLDWING DOCS STORE DOES NOT WORK ON THE 84 LTD'S?? NOT ON DIGITAL GAUGES !!
ANY COMMENTS??

My 84 would top out at 14.3volts and start from 13.4 at a idle.
The digital ones do not use a 7 volt regulator.The digital display and sensor parts are regulated by a display board 5 volt system.
There is a model of the 1200 that has mechanical gauges for fuel and temp that do not use a 7 volt regulator too.
It may be the Aspy.

did 90 mile trip to-day ,
key on..11.5 volts
idle speed......12----13 volts
cruising speed 15.1 volts.
went down at one stage to 13.8 volts then back up to 15.1 v

any ideas??

to-morrow I will fit a relay as suggested by VIRGIL

thanks for reading this

Stable output from the R/R module is reliant on 2 things.A absolutely perfect ground(scrape it clean)at the regulator ground lug and connections.,and accurate battery voltage on the "sense" wire (black/white).
You use the black/white wire to operate the relay (cut it loose from the R/R module)and a fused (5 amp) #14 wire from the battery post to feed the switch contacts.The contact feeds the R/R module.

once again saved by the Guru Virgil!!!
I fitted a relay and added an extra ground cable
I rode 260 km' today and the voltage stabilized at a constant 14.3 volts
Last but not least one more question
The neutral position light does not always come on the gear indicator on the dash.
When stopping the neutral gear position is hard to find
Any info. will be thoroughly appreciated
Thanks again
Brian

Up front of the engine is a electrical cable.one wire should go to ground when in neutral.its the neutral lamp ground.
Often the switch is bad that the wire hooks to.the bad news is that you would have to remove the front cover to get to it.50/50 chance that it can be repaired.Usually just replaced after it's verified bad.

The 7 volt regulator is used as a secondary regulator specifically for the fuel and temp gauges on GL1000, GL1100 (without digital dash) and GL1200 Standards (and some Interstates) with analog gauges. It is not the same as the main 12 volt regulator.
