The clocks on these scooters are notorious for failing to work. Fortunately, it isn't usually some esoteric solid-state device that is causing the problem - it's just a battery, or battery contact issue.

Unfortunately, Honda's engineers made this as challenging as they could. (1) it is quite difficult to get into the battery compartment: there's no indication of where or how to pry up the cover, and if you do it badly, replacements are not available. (2) once you get the cover off, the battery compartment is inaccessible without some kind of tool.

Ah, come on guys; it didn't have to be that complicated - and it isn't even weatherproof!

Fumble one of those teensie little screws and it will disappear into that gap in the panel below, and end up inside the instrument panel, or on the floor (they are black; invisible on concrete, grass, or anything else.)

They are machine screws requiring a jeweler's Phillips #0 driver.

As they come out, hold each to the screwdriver with a fingernail. Have somewhere nearby to put them.

Then you find that there is no way to grasp the battery holder, and since it's recessed, you can't get it out of the panel. Sh--.

Hey guys, is this why you lost?

If you thought you were done with the frustrations, think again. With the battery holder removed, you see why the clock doesn't work...the holder does not keep the battery against the contacts!

So now you have to fish the battery out, and lacking a magnet pick-up tool, you are going to have a tough time doing it. A pair of tweezers might work - but needle nosed pliers probably won't, as seen here.

Having removed the loose battery, replace it with a new one. You'd better clean those contacts too, because you sure as heck don't want to go through this again any sooner than necessary.

I suggest a pencil eraser to start, or a manicure sanding board (use the fine side) and a soft bristle artist's paint brush to wisk out the debris.

Now for my trick: how to force the battery firmly against the contacts when this monster is reassembled and you can't see what's going on inside it.

I'm not only clever and good looking, I'm cheap too!

Cut a shim (or two) from something like a cereal box flap; insert the shim(s) between the battery and the silly little non-fitting clip.

Be sure to keep track of the position of the contact surfaces of the battery while you are doing this.

If you want to get fancy and use something "springy" it's okay with me, but this cardboard has worked for me for many months without any problems.

Done!

Note the time -- which, of course, you have to reset after changing the battery; again "blessing" the Honda engineers who opted for the simplest clock circuit available so you have to go "all around the clock" if you make a 1 minute overrun.

If you hold the "ADJ." and "HOUR" (or "MIN.") buttons simultaneously for long enough, the display wil eventually begin to change automatically, but v-e-r-y---s-l-o-w-l-y; so if you are near the end of an hour, as seen here, it might be better to wait a few minutes before resetting.
