Ignition switch & LCD panel

Post by Mh434 »



Ok, this one's weird. Recently, I got on the bike, fired it up, and rode off - only to realize that my LCD panel was blank. Also, the stereo, CB, & intercom functions were completely dead. Most of the bike's other functions worked still. After about 1/2 hour of riding, the LCD panel suddenly came back to life like nothing ever happened.

Since then, I've discovered that I have to watch the LCD display while I'm turning on the key. When I turn it to the first detent, the clock always comes on, with the correct time. About half the time, though, when I turn it to the next detent ("ignition", for starting) the screen goes blank & the radio, CB, etc. become unresponsive. No lighting in the panel, either (although the rest of the lights work). When that happens, turning the key gingerly off and on *usually* results in the time display remaining on, and all functions work normally (at least for the time being).

When it does its fail routine, I hear a distinct "click", that sounds like it's somewhere below the left fairing pocket. When it works properly, no discernible "click".

Anybody else run into this? Any idea what might be causing it?

Unfortunately, I'm house sitting in Canada right now, and don't have access to tools beyond what's in the Honda tool kit onboard. Of course.

Sounds like the acc contacts in the ignition switch are getting flaky. Does the 2 second lamp test at key on work?
When the LCD is off, see if the hazards are also dead.

Had you removed the shelter at any point prior to you noticing this particular malfunction?
Has the radio been disconnected at any point prior to that?
Perhaps the radio connector is not fully seated and it is not coming to life when you first power up the bike.

I'll have to try that. I'm always reluctant to use my hazards as the switch always sticks on (although I've disassembled & cleaned it numerous times), but I guess that's the first, best step....

I haven't removed the shelter in years, and I don't think I ever disconnected the radio connector. I still haven't figured out the "click" sound that happens when it fails. Sounds like a relay, but I don't know of any under the left fairing pocket.

I was just looking for other items that are powered from the accessory circuit. The speed sensor for the cruise control is also on that circuit.
The easy thing is just to check for power at fuse 10 when the key is on but the LCD isn't working. If so, your ignition switch needs cleaning or replacement.

I'm really thinking it is the ignition switch. If everything doesn't come on, and I turn it off & on, it generally comes back to life. Once it's up and working, it stays working as long as it's running. Guess I need to try cleaning the ignition switch, however that's accomplished! I do have a can of electronics spray onboard...

I have noted that the cruise control stopped engaging a while back, but I'm not sure it's related to the current issue.

Well, the bike hasn't done this in several days now. As long as I turn the ignition key slowly & purposefully the LCD panel remains on into the "run" position & everything works. Looks like it's the ignition switch....probably a bit of crap down there. Electronics spray will be my first go-to to see if I can stop it happening again, although with it working okay now, it's tempting to leave well enough alone. The bike is my only transportation now and I'd be totally screwed without it.
