OMRON G8MS-H30 relays

Postby RFW&LMW » Sun Nov 29, 2015 6:36 pm



First time with a Goldwing, & I have been reading a lot about these relays on this great site. I was wondering how many of these relays are there in my 1995 SE Wing & if there is a chart of some kind describing the location of the relay & the problem that might occur relating to a given relay. ( Does this make any sense to any one?) Are the relays all of the same type & or part number? Any help would be much appreciated.

Depending on the year and model of GL1500, there are between 7 and 9 relays, and most are interchangeable. They control pretty much everything electrical on the bike. Which relay controls what varies on some years, but on my 2000, this is their function:

I didn't want to take any chances with a bike coming up on 20 years old. I replaced all 7 (Bought them through this web site.) even tho I wasn't having any problems. Relays are a electro mechanical device which have a life span, and there is only a certain number of cycles before it will fail, or act erratically. Better safe then sorry.

Thanks for the feedback Greenwinger, when you said you bought them through this web site were you referring to the site that WingAdmin posted & if so do you remember the cost after clearing them through customs & so on?

The Admin just left you a link. These are by far the best price on these relays I have ever found.
Sorry, can't remember how much it cost me to bring them to Canada as I did it some time last year, and the Canadian dollar was in much better shape then it is now. What ever the cost it is worth it. When the relays begin to fail along with erratic operation of the controlled device they can cause a heat build up in the wire connectors which means you may have to re-wire as well as replace the relays. And the last thing you want is a major electrical failure 1600Km.(1000 miles for our US brothers) from home.
I believe your relay box is the same as mine, these relays will replace 7 of the eight in the box, the 8th is a light blue colour and controls the front turn signal running lights and is not interchangeable with these relays. I didn't replace this 8th one as it seems to be working fine,doesn't control a hight current circuit and if it fails, wont leave you stranded on the side of the road.

I would definitely buy new relays if possible, but in the event you get caught with your pants down like I did and can't find a store that has what you need, here's a post I made listing some alternatives .

Hi to all and Merry Christmas and happy new year as well. I have a question. I went out on Christmas day and with a full charged battery and about 60 degree weather decided to go for a ride on my 98 1500 wing but all I got when I turned the key was very dim lights and nothing but clicking from the relays area. I cleaned terminals and checked battery and even threw charger on but same issue. Very dim to non existent lights and clicking. Could this be a relay problem? I just ordered a couple relays from this site in case. Thanks for any insight you could give

Check the voltage on the battery. At rest it should be over 12V, with a start voltage (voltage when you push the button) of no less than 10 or 11V.
To me, and while I'm new to wing's, I'm not new to motorcycles.... but it sounds like the battery gave up the ghost AKA: YSDS.
Yuasa Sudden Death Syndrome....or insert the brand name at the beginning. When a plate gives way or goes 'flat', it's sometimes sudden to the point of 'I just rode here, how could that happen'.
Check the fluid level in the battery, check the voltage, check the local auto store for a 'we give free battery tests' sign.
Just my opinion.

Thanks for your repl. The battery is a new gel purchased in June. It is fully charged and I even had my heavy duty charger on it too. I am hoping that maybe it is a faulty relay and that would be the easy fix. Might have to trailer it down to the Honda dealer and get her fixed.

Even fairly new batteries can give you issues. Best to go and get it tested, with a load tester.

By "Heavy Duty" do you mean high amperage output? If so, that could cook your battery. Motorcycle batteries have fairly small sizes, (which usually relates to output), so by hooking it to a Heavy Duty Charger, you could be doing yourself a disservice. More better to charge it slowly, but not for longer than 12 hours, unless it is a "smart charger".

Yes it is a smart charger. I set it for gel and 2 amp. Thing is, 2 weeks prior, I was out riding for a spell and then we got into a rainy / foggy patern, and since I keep the bike in an enclosed trailer things get damp inside from condensation. I'm thinking maybe there is wires or connections somewhere that are shorting out and causing this issue. I'm going to take the battery over to Napa and get a load test done to see if it is bad cell or something. This will be the 2nd yuassa battery in 3 years to crap out if it is faulty. I do notice that when I disconnect and reconnect the battery I can hear the cassette deck run and then stop. That is with the key off too. Wondering if that is normal or if I have issues there. Radio works fine otherwise. Thanks for the advice. Happy New Year.

Normal. At least with both of ours if it's not with everyone else's ;)
That's why they call it Yuasa Sudden Death Syndrome. "But I just rode it here"....it just happens. Would not be the first, will not be the last. Gel or not. In my experience it's usually the regular lead acid, but it doesn't seem to matter. I haven't seen it happen to a lithium or magnesium battery yet though.

Unfortunately lots of electrical on the wing, with a whole lot of wiring that goes along with it. Doesn't take much of a drain to kill a battery, and I've seen a wet short in an electrical system turn a fuse into a very low wattage light bulb that killed a battery long before it blew the fuse. (-80C laboratory freezer...long story :| )

You could have a wet conductor...something that only kills your battery when it gets wet...see above for 'a lot of electrical'. I learned (thanks dad!) a cheap fix early on...di-electric grease on every connector you ever get your hands on, and base of every bulb you can find. (pop 'em apart, check for corrosion and clean it if it is, liberal application of grease in the connector, and squeeze it back together. My first enduro (KE175) would die in the bloody rain before I took care of all the connections and bulbs. After that was I could take it through streams up to the carb and never had a single problem, even the next day.

Also, check your both your battery terminals for tightness, the connection to/from the starter relay, and the path of ground to a solid corrosion free connection points. Not sure on the wing (yet) but my Concours has the starter relay mounted upside down...and if it ever gets wet, it fills with water and even dry nothing will start the bike outside of jumping the relay.

Check the simple stuff first, you'll have more than enough time to check the complicated stuff if it's not the simple stuff. Unfortunately, that I can promise you.

Good luck, Merry New Year!

Good battery or bad, the headlight should go out when you hit the starter button. If it does not go out, or just goes dim while trying to start, then you may have a problem with that relay. Most batteries will not have enough amps to start the bike while the headlight and taillights are on, so the relay is supposed to turn these off while the starter is being engaged. A quick test would be to pull the headlight fuse and try to start. If this doesn't reveal anything, I would probably pull all the fuses not needed for the engine to run and see if that narrows down where the problem is. I.E. pull the fuse for the headlight, tail light, horn, accessory, engine fan, etc. but leave in the ignition, fuel pump, etc. and see if the engine will start. If it does, then start replacing fuses until you identify the problem. Of course, if you pull the engine fan fuse, don't run the engine long without replacing it.
