Turn Signals connected to clutch lever?

Postby Cleverator » Tue Jun 12, 2012 8:09 pm



OK, this is pretty weird to me. I have a '91 Aspencade and just tonight when I was out for a ride the two in-dash hazard lights seemed to come on, kind of dim, but steady on - not blinking. Then I noticed that when I signaled left or right the signals blinked really fast, almost like there was a load on the relay. Then I couldn't help but notice, when I pulled up to a stop light and engaged the clutch, the hazard lights went out and the turn signals acted normally (as long as I had the clutch lever pulled in). As soon as I let the clutch lever out, the hazard indicator lights come on and the turn signals started that quick flash again. Finally I noticed that with the clutch lever in (hazard indicators off), when I pulled on the brake lever the hazard indicators went on again... I couldn't be any more confused on where to start. Any help or ideas really appreciated.
Thanks

Personally,I'd start at the lamps.A broken element shorting the inside(substitute another good one) ,or a bad/corroded ground in the socket.etc.

Anytime you have electrical weirdness happening that appears to be resolved when you operate seemingly unrelated controls (clutch switch causes signals to start working) it's almost always a bad ground. A ground goes bad, so the item doesn't work correctly. When you use the unrelated control, it provides a ground through a different path, and the item works again.

Thanks WingAdmin, virginmobile; These both seem reasonable to me. Lamps will be easy to verify - hopefully that's the thing 'cause tracing and finding a bad ground is going to be painful :(

A loose connection won't cause the lights to come on dim.a corroded ground will lend to a backfeed through them.
As a quick test for grounding problems,I've hooked a wire direct to the battery negative post and attached it to the lamp green ground wire.effectible bypassing it's normal ground.if it returns to normal,I locate the ground point and scrape it clean.

As Wingadmin stated, I would be looking for a bad ground at the handlebars. It sounds like things are getting grounded via the clutch cutout switch.. That will lead to some very strange things happening..

Got it! First let me state that I did not buy this bike new nor did I make any after-market changes. What I have is what i bought (only a year ago). I checked all the bulbs and thoroughly checked the wiring harness on both sides of the handlebar after removing the covers... no luck :( . So, with the wing up on the center stand, I closed the garage doors, turned off the garage lights and had a look at the running / signal lights on the bike. With the bike in neutral, everything that should work did, but as soon as I put the bike in gear that's when things went wacky. Turn signals and hazard lights blinked really fast - like the relays were overloaded; reverse would work for about 1 second then quit (take it out of reverse and put it back in - get another second); cruise control would turn on but not engage; pull in the clutch and the signal lights would work again, put on the brakes and the hazard light indicators would brighten ...
What I did notice with the bike up on the center stand in the dark garage was that as soon as I put the bike in gear all the running lights in the trunk / saddle bags went out. And I noticed that the relay that controls the trailer lights was clicking REALLY loud. So I pulled the main plug on the rear running lights (big blue connector on left side inside a plastic cover), removed all the electrical tape on the harness and un-wired the trailer relay and everything up front at least worked OK. Now ... the trailer relay is connected to the wiring harness with those blue fold-over easy-clips. Those things should be illegal to use in a bike :evil: . I removed the easy-clips, properly soldered the trailer relay in and reconnected the harness.
Everything works!! So there was a bad ground in the trailer relay ...
And finding that was more good luck (with a lot of help and ideas from GoldwingDocs) than any perceived electrical / mechanical abilities on my part.

Thanks guys!!

Glad to hear you got it solved.. Whenever I buy a second hand bike, the first thing I do is remove all the electrical add-ons that it has acquired over the years, any that I want to keep I solder and seal with heat shrink tubing!! I agree with you that the plastic scotch block connectors should be banned from use on all vehicles, not just motorbikes!! :D

Have fun riding.

As with any connector used, it is best to use silicon grease or dielectric grease in the fitting to keep water away. After 40 years doing electrical work I can say it's not the device, it's the way it's installed. When there is a chance a joint will get wet it needs to be sealed.
