'84 GL1200 was charging now isn't

Postby Pilotgoldwing » Thu Sep 05, 2013 4:23 pm



I just bought an '84 GL1200 Goldwing Aspencade. It starts and idles fine but out on the road if you open her up she sounds like she is only hitting on 3 cylinders. I had one of the lighter volt meters so I stuck it in the lighter socket before I left out. Initially when you advanced the throttle the volt meter would read about 13.5-14.0 and then at idle it would go back down to 12 volts. After I did about a 15 mile ride to see what I could find wrong, I noticed the rough running at higher speed and the no longer charging issue. I checked all 4 spark plugs and they are all sparking when the engine is turned over. Also on the ride I went over a bump leading onto a small concrete bridge. It wasn't to bad but for some reason the display panel went blank and the engine lost all electrical power. I coasted to a stop, turned the key off then back on and it fired right up and I continued home. The bike had been sitting for about 3 years. Any thoughts?

You may have a loose and/or corroded terminal on the battery or somewhere else. Start with the battery terminals. Do not tighten them. Try to loosen them instead and see if one turns easily, indicating that is is loose. Then loosen and remove both terminals, negative first. Clean them and reassemble tightly. If that wasn't the problem do the same procedure on the fuse block and the main fuse.
Good Luck.

I checked the cables as well as following Saunders You Tube troubleshooting videos. I think my issue is the stator is bad. On the three yellow wires I have 4 volts, 2.5 volts and 1.8 volts. I believe each wire should have approx. 4 volts on them. My dilemma now is whether to farm out the work, try to do it myself, or put a poorboy alternator conversion. Any suggestions?

Poiltgoldwing Did you check the stator using a/c setting on your meter or dc. It should be set for a/c and you should be reading at least 40 volts a/c on all three legs.--------------------------Hal

Hal,
I followed the video and it showed testing on DC stating there should be 4 volts per leg. I will go check now on AC and see if that is different.
Thanks

Hal,
This test didn't fare any better. On the AC setting I got 14, 8 and 4 volts. Still looks like the stator and I am still in my quandary. :cry:

Well from what your readings show you I would say the stator is gone. Just my 2 cents but if my 85s stator goes out Ill be putting in the poor boy. Why waste the time off pulling the motor out and putting in another under rated stator. At least with the poor boy you have more power to play with and a heck of a lot easier to replace a alt. then a stator. Again just my 2 cents And I see you also live in Indiana,not that far away.----------------------Hal

Hal,
I Agree On The Conversion idea. Do You Have Any Idea How Long The Conversion Should Take?

If you have all the parts it should only take a day or two,you need to look at some of the threads about how to do the poor boy conversion. There is some grinding involved but from what I see its not to hard,just depends on what tools you have and if you can wrench!--------------------------------------------Hal

Well it was time to get creative. I will need to ride the bike about 30 miles to the shop that will do the conversion. My concern was that the little battery wouldn't hold enough juice to make the trip. With that being the case I did a little rigging and installed a second battery in the left saddlebag case and hooked it up in parallel so I would have the capacitance to make the trip. I think I have answered another issue in the process. When I got done with the temporary installation I went out for a ride and it was amazing how much better the bike ran with more juice. My volt meter still only went up to about 12.4 Volts at cruise speeds, but this should get me to the shop so long as I don't use turn signals or the radio. Life is Good!

Hi guys like yourselves I've got charging problems I guess mine are a little more simple but I guess not for me. I've been experiencing intermittent charging problems since I purchased the bike 5 years ago. (1984 Interstate 1200) It’s finally come to a head in that the bike won't keep a charge now. I've tried installed a new battery - a Honda bike mechanic suggested this before trying anything else. In Mike Saunders video for checking the stator voltage coming from the stator by Neil (forum name-ccsailor) my stator outputs are on 2 legs 8 volts each, the 3rd leg only puts out 4 volts with meter on A/C scale as instructed and rpm @ better than 3000.
I also chopped out the plug as suggested, although I don't think this issue mattered as I didn't see any corrosion, or the plug didn't seem faulty but its dust now.
In addition I check the voltage on my battery (battery sitting on the bench fully charged 12.6 volts) whereas the forum suggested it should be putting out 13.5 or 13.9 volts D/C, mentioned this also to my Honda mechanic friend and he said that he typically doesn't see juice higher than 12.7 volts off a battery nowadays?????
So I'm stuck at the moment trying to figure out if I should go ahead and pull the motor and do the stator rewind or recheck the voltage again (not sure what's that going to prove again).
Any suggestions anyone has I would appreciate, other than reverting to the "poor-boys conversion" to an outside alternator - to me that makes the bike look like dirt!

Your battery is fine, your stator isn't. Your choices are pull the motor and hope you get a good stator when you replace yours or go the conversion route. As far as the dirt comment, that was mildly offensive. With the small alternators available, and done right, you have to really look close to see the conversion has been done. That is unless you notice the bright lights and normally functioning radio. Either way get ready to spend some serious coin. Good luck.

My apologies about that pilotgoldwing didn't mean to inject my opinion here on the conversion ...... appreciate your reply and suggestion.
