  • The lights are on...

    The turn signals on the '80 XS1100G I just bought are out. No lights at all from the front or rear-except the headlight and tail/brakelight. Since the previous owner had thoughtfully supplied me with a used turn signal switch, a buddy who owns a Harley shop came over to see if that was it.
    He found juice at the 4 lights, but the left rear bulb socket is corroded and we couldn't get the bulb to light. All the others came on at some point during the testing.
    The thing is, none of it was consistent. The right side lights would come on and blink, but the left front came on with no blinking-nada from the rear. Sometimes the hazard flasher unit would work and you could hear it doing so-other times no. Sometimes you'd put the right blinker on, but the left would light w/o blinking. Sometimes the indicator light would come on, but not the lights. And we never got running lights to come on.
    The bike has a fairing, and at one point the front end was swapped out with a non-fairing bike. I'm not sure if the signals worked after that.
    My buddy thinks it's the flasher unit, but that doesn't explain the lack of parking lights. Could the bad socket be causing the problem? A combo?
    There's an ugly jumble of wires in front of the steering head that somebody stuffed into a leather bag, probably when the swap took place.
    My buddy is an ace with Harleys, been doing it 35 years, but he thinks this will take somebody familiar with the brand.
    I live in Taxachusetts, so have to do the yearly anti-up inspection. Any help would be greatly appreciated. Thanks.

    Jamak, your location would be helpful, there could be some one near you from the site. The bag is for the wires that are used when you have no fairing and have a headlight bucket and signals. You need a manual with schematics. sounds like you need a lot of connection cleaning and wire tracing. I think there is no problem with your flasher unit, just a lot of coroded and maybe grounded wires.

      Go to user CatatonicBug's website and download the "Aftermarket" service manual on the right hand side. At the end you'll see a wiring diagram. Check the turn signal system as best you can. There might be a colored one posted somewhere here, but I'm not sure where.

      If it is something intermittent and spastic, you probably have some shorts and/or bad connections. Go over that bundle of wires very carefully, especially where it looks like there may be bad connections on the wires coming from or going to your blinkers. If there are any wires that are just loose and you can't tell what they go to, tape the ends over until you find out so they don't cause any shorts/blow any fuses.

      There are others that know much more, but that's where I would start. They'll chime in here in a bit, just give them a minute or two.

          The bag was normal with the Vetter fairing.
          The wires/connecters from the head light were placed in them.
          Take a look to see if you have pinched wires between the left fork and the stop. (wires to the fairing)

          While I recommend taking a couple hours and clean all the connectors/grounds on the bike your current problem in part maybe the ground wires on the turn signals. Only takes one with a little corrosion to screw up the side it's on.

          Sometimes the sockets can be salvaged, remove/clean and use a little electrical grease. The contacts in the socket can be FUBARed. For a temporary repair I've put a glop of solder on the end of the wire where the contact was missing. Some sockets be so rusted they fall apart tho...

            Electrical woes

            Thanks men.
            I live in E. Brookfield. If there is anybody nearby who can help, the beers and BBQ are on me!
            My buddy is very sharp-but he's HD thru and thru. He's coming over after 10 hours at his shop, so I can't ask more of him.
            I, unfortunately, have always sucked with wiring. It may be time to get good, because I don't have the dough to pay a shop.
            I'll start going thru the wires to see what I can find, and I'm getting a new flasher, and hopefully fix the light socket-or replace it.
            The weirdest part was how the lights would go on and off without rhyme or reason-but I guess that's how shorts are.
            Thanks again, and I'm open to any more brain power.

              clean all the wiring connections and apply dieelectric grease(water-proofing)

              start with that.

              find yourself a toothbrush sized wire brush and clean terminals, front to back.

              this will also help the bike run better to.

              replace the fuse box with an ATC fuse block, this will also help.
              see this: http://www.xs11.com/forum/showthread.php?t=14052

              the original fuse holders do not clamp tight and can drop out intermitantly.

              Good luck!!!

                lights are on...

                I replaced the flasher unit with an after market 3-prong, and cleaned all the connectors I could find/get at with a wire brush and a little brakeclean sprayed on a rag to get the grunge off the wires and outside. I used sandpaper on the flat contact connectors.
                Still nothing from the left rear-no light at all. Flashers work fine on the other 3but no turn signals or running lights-in fact the lights don't light at all as turn signals. I've tried these tests with the fairing plugged in, and I've jiggled any suspicious looking wires as I held the signal swittch on-nada.
                I found some bare wires on the signal cancelling unit, and the unit looks pretty beat. Could that cause all this grief?
                I'm also having a helluva time getting the left side cover off at the bottom. It looks like it should have a rubber plug/mount, but all I can see is a plastic prong coming off the cover into the hole. I tried pulling and prying as much as I thought advisable, but no go. I've read you guys saying these can be hard to get, so I don't want to smoke it.
                The bike runs pretty well, but I can't ride it until I pass Mass, inspection.
                Advise, pointers? All are appreciated big time. Thanks.

                  The left side cover comes off with your key. Near the bottom of the cover you will see where the key goes. It only turns a little bit and the cover should come right off. There are no running lights. They are signals only.

                  I am out on the South Shore. If I get a chance I will try to make it out that way in the next week or two. All depends on work and life lol.

                    Aftermarket 3 prong will NOT work! Have to go with a two prong if aftermarket, and it will work one way and not the other (gotta try it both). Also if you got 4 ways (80 or newer) it's likely the connections on the 4 way switch. Take the pod apart and get that switch out and you will almost for sure find the wires have come loose. Clean them up and solder them back to the terminals on the switch to get them working again, then it may well be fine. It all goes through that little 4 way switch, and once the wires come loose (and believe me, they will) nothing works right until you fix it.

                      the lights are on...

                      Thanks on the cover info, and all the rest.
                      The 3-prong was sold to me as a replacement that supposedly sent a 'stronger' replacement for the stock unit, but you're saying ANY aftermarket is NFG-correct? It should be obvious that I am an electrical moron by now-excuse the repeated questions.
                      Also, the four way? Which switch are you referring to? That sounds like a likely culprit, as you say. I just need to identify it. Thank you.

                          As pete said any 2 prong will work - but maybe get an electronic one so if you want to use leds in the future you don't have to buy another one. In addition no one has found a 3 prong aftermarket unit that will work. None of them are right because the factory 3rd prong is for the self canceler input. Who ever sold you that flasher probably figured the stock one was a standard 3 prong and it isn't, its special to Yamaha and that is the only place you can get them.

                            One thing I forgot. Make sure you are using the 1156 bulbs and not 1157.

                              the lights are on...and blinking

                              all except that left rear, which hasn't come on since I started this movie.
                              I was using an 1156, but since I was at the dealers today, I picked up 2 Yamaha bulbs to boot.
                              The socket is nasty, so next step is to take it apart and clean it up to see if it is salvageable. I'm getting close.
                              I picked up a 2-prong as suggested, and the flashers only worked with the key on, and the flasher switch in the off position. I reinstalled the cancelling
                              unit, and voila! Emergency's w/ the ignition key off/flashers in the on position, and signal lights on and blinking-except the one.
                              Many thanks to all who responded. I appreciate your patience and input.
                              Now to get that bulb to light, change the oil, and get this beast inspected.
                              Still no horn(no button, but the horns work), but the local shop says they'll let me slide with a bulb horn. Once it's on the road, I'll try to hunt down what I need. Stay tuned and thanks again.
