Tachometer woes

[Gregg]

I have scoured the Tech site for links to tacho problems and have found many posts that discuss the earthing issues etc. But my Veglia tacho's light suddenly went dim and then out completely - I consulted the site and my workshop manual on CD and removed the tacho reasonably easily ( lucky Huh ?)except for 2 of the mount bolts deciding to become loose (which I plan to stick back solid with a metal putty as has been suggested by many posts & links). The bulb is dead so I thought it should be just a matter of replacing it.

My problem/handicap is that I cannot remove the bulb - the mounting of which I am still recovering from the shock of Veglia or Guzzi's design ineptitude. The nylon push seal is infantile - the spring is haphazard, and the mushroom composite contact plate is random all just to mount a bulb, but I guess you have all heard that before !

When I finally rounded these projectiles all up from the garage floor 10 feet away on dismantling (& the subsequent beer consumption immeadiately afterwards required to remain sane).

I then focused back on the bulb.

I cannot for the life of me see how you remove this dead bulb without dismantling the tacho.

Would anyone have been here and done this before ?

I am half inclined to just put it all back together and ignore the problem of an unlit tacho, but if it is an easier fix than it appears to be, then I should do it while I have the bike apart this far.

Appreciate any advice or even an offer for sale of a 2nd hand replacement white tacho with a working bulb !

 

P.S. I have removed the bulb shroud that came loose in the bottom of my headlight - talk about keyhole surgery - what a delight and decided misguidedly that I would fix the tacho light while there ( mistake 2)

Gregg, I posted my solution for this a couple of years back for the Veglia instruments, but can't take the time to search it out right now. The stock bulb sockets pull straight out from the back of the instrument cases. The stock sockets are so cheesy that I decided they just wouldn't do -- they look like a point of failure waiting to happen. I found higher quality generic replacement sockets at the local auto parts place that I managed to bodge in, which I considered a great improvement. I haven't had a bit o' trouble with 'em. Sorry, I don't have mfgr or part numbers, but I reckon you could do as well with one as the next.

 

Hope this helps.

Thanks for that, I will just use a bit more force as my bulb just didn't want to move and I wasn't game to take a chance that they would give. Logic told me they should just pull or screw out - but I also wouldn't have been surprised knowing my luck if Veglia had built the tacho around the bulb either.
