Meter 'Select' Switch Failure

[donnvjuan]

Folks,

I'm trying to avoid buying a complete new meter and would love any thoughts or input.

My 'select' button rubber wore a small hole in it that I didn't notice and of course I washed it. The next time I turned the bike on the switch failed changing my MPH display to KM and making the switch further inoperable. I've removed and taken apart the meter and the switch connector has some decent corrosion in it. I'm using some electrical cleaner and some light scraping to possibly recover it but I'm not optimistic.

Any thoughts and advice for a new guy on the forum would be greatly appreciated.

Thanks

if your bike is an 07 then check it might still be under warranty then you can claim for a new set of clock

Do you have a picture of the switch? You can probably get a new one from mouser.com or digi-key.com and solder it onto the board. The trick is finding the part so that you can order it.

Fred,

Hope you get this and thanks for the tip. If I did this right the picture is attached the pic with SW1, the right of the two push buttons. I'll do some searching and appreciate the help.

Post a pic of the backside as well please. Is it a "surface mount" or a "thru-hole mount" switch? I am certain you can find a replacement and rework the PCB for just a few $. If you can't pull a part number off the switch, you can measure the contact (pad/pin) spacing and the diameter of the switch and match up something similar. Radio shack might even have that switch in stock.

Let us know if you have any questions on the rework process, you'll def. want to use low-wattage iron (temp controlled if possible) to prevent PCB damage.

Pic is attached of the backside. Not a professional on this but looks like a through hole mount.

Dimensions from a ruler...don't have a caliper
Pin spacing: 5 mm
Switch Height: 8 mm
Switch Diameter: 6 mm

Part Number: Not visible

I'll be looking as I get the time. I'll probably take it to a local stereo repairman that should have some skills for this. A couple of bucs for the part and maybe a quick minute for labor as I don't have tool for it, nor the regular need to buy one at this point.

For reference the resistance on the good switch is 18 ohms (200k) and the bad is around 2 ohms. I put some WD40 to break up some of the corrosion and the resistance went up but after using some electrical cleaner to clean it out it went back to the 2 ohms. Still trying to do what I can but that is probably the extent of that effort.

Thanks for the help

yes that is thru-hole.

page 5, fig 8, then go to page 6, this one is available it is 7mm high:

6mm Round Shape for Mounting Efficiency 2 7 6 260gf 15 20 100K P8084SCT-ND◆ .38

there is also a 9.5mm H which I believe is shown in fig 9.

Stereo shop should be able to quicky make the repair (and they might even have a part that will work), or you can use a low-wattage iron, some pcb safe flux, and some de-soldering braid to remove the old one.
