Yamaha RXS100 - Main Beam Warning Lamp Replacement

[Dr Sangrado]

Could someone please tell me how this is done. The Haynes manual explains that the top cover of the warning lamps compartment, which is retained by two screws under the mounting bracket must first be removed. It also says that all other models have the screws positioned on the top (the most practical place for them). I can see the screws but as they are obstructed by the headlight unit, this appears to have to be removed to gain access. I can't see how to do this, if it is necessary, nor does the Haynes manual offer any guidance. Thank you for any advice.

Are you referring to this Doc? 

This is on my Honda 400/4 but from your description it sounds similar

 

 

A photo often helps...

 

[Dr Sangrado]

Yes, that's a similar item. There is less than 19mm clearance between the front screw head and the headlamp bowl so unless there's a special screwdriver that fits, the headlight needs to be removed; as far as I can see. I could raise the speedo and tacho but I don't think that would help.

[NE0]

Its quite possible that you're going to have to remove the headlight to gain access, having said that, whilst the haynes manual might not mention how to change bulbs in the module, the smaller Owners manual which would have come with the bike is the likely place to find instructions on how to change them.

Thanks for the links. It does look that the headlight will have to be removed; although it seems strange that Yamaha would choose such a difficult and time-consuming way to replace a bulb. Perhaps in the case of the RXS100 its designer didn't want unsightly screw heads spoiling the appearance of the instrument cluster; although I would prefer the screws to be visible and accessible.

Hopefully fellow RXS100 owners, with experience of changing warning lamps, will know of a quick and easy way to do so.

I wouldn't put to much hope on that one Doc, so few members post these days and the chance of a fellow RXS100 owner coming to the rescue,....you will have stripped down the headlight and replaced the faulty bulb long before then!

[NE0]

I reckon, it might be a case of unscrewing the headlight bolts slightly so the headlamp can be swivelled facing downwards, that might give you enough access to those two screws to the console.

From what I remember of bikes from this era, turning the light won't help, it will still be in the way...
As a different direction, what about the clock unit? What's holding that on? Would it be easier to displace the whole clock unit?

[Dr Sangrado]

Thanks All for the advice. I've finally checked the bulb, and that of the Low Oil Level warning one, which is supposed to illuminate as a check when the bike is in neutral, according to Haynes, as that too didn't work. As can be seen from the photo it's quite a palaver, but there's no other way. The bulbs were intact, which I wasn't expecting, so maybe one day I'll check to see why but at least the Neutral light works.

[Snakebite68]

Congratulations..? lol

[NE0]

Looks like you dismounted the headlamp in the end to drop it out of the way.  I'm sure the oil light and neutral light only come on together with the key before you actually start the motor, once running the oil pressure keeps the oil light off.

 

Incidently, I got offered 10% off from those  owners manuals from the ebay seller simply by looking at them for you. I declined the offer.

[Dr Sangrado]

Yes, I had to resort to disconnecting the headlight bowl. The Haynes manual explains that the low oil level lamp is operated by a float switch which is a press fit in the top of the oil tank. This is wired through the neutral switch so that when the ignition is switched on, and the machine is in neutral, the lamp comes on as a way of checking its operation. As soon as a gear is selected the lamp should go out unless the oil level is low.

low oil level lamp is operated by a float switch which is a press fit in the top of the oil tank....

ahhhhhh, ITS the two stroke oil tank low level warning light, I thought it was referring to the engine/gearbox oil level. My mistake.
