[Tach Failure]

As I was prying a small piece of the counter weight fell out of the unit.  Problem #1 identified.  Upon removing the mechanism from the housing I had the second full counterweight fall out.  Problem #2 identified. 

 

Upon close inspection of the contact wires which many have said that they have found detached I see one is attached and the second appears broken.  Problem #3 possibly identified.  It is not clear to me exactly where to re-solder this second wire to.  Searching the forum I read that a few have done this and posted pictures of it but those picture links don’t work anymore.

My next planned step is to put the counter weights back together with a little drop of superglue and test the tach without attempting a re-solder and see what happens.  I don’t think this will work but I will try anyways. 

My question to you who have done this repair before, do I need to re-solder that second wire to something and if yes, to where?

[Tach Failure]

 

Hi everyone, I have recently acquired a 2000 V11 sport and it has they typical bouncy speedometer and non-working tachometer as many of these Veglia Borletti gauges do.  I’ve spent many hours reading the many threads on this topic here in the forum and on other forums as well.  This research has led me to the decision to replace the Veglias with the Speedhuts.

HOWEVER, since I have made that decision, I figured I have nothing to lose by attempting a repair on the instruments and documenting what I find.  Also adding some pictures along the way for anyone else who may want to attempt this in the future.  Since the speedometer kind of works I went in on the tach first. 

These are the threads that I found most useful:

2007 https://www.v11lemans.com/forums/topic/12441-open-up-your-veglia-and-close-it-back-again/

Step 1:  I played ‘round robin’ with the relays to rule out a faulty relay.  I cleaned the relay contact points with Deoxit as I went.  Nothing changed.

Step 2:  I opened up the instruments housing and tested the signals with a multimeter.  I displayed a 12V on the red/black power line.  I displayed an increase in frequency while turning the throttle on the yellow/black line.  This tells me that the electronics are fine and that the issue is mechanical within the tachometer.

Step 3:  I removed the tachometer from the dash by removing the three spade connections and by snipping the little black ground wire for the light bulb.

I have the early white faced version with a date stamp of Jan. 19, 2000.

   

Step 4: I removed the bezel by prying it up using one of those little screwdrivers which are pre-bent.  After about 10 minutes of this I had to wrap the screwdriver with some tape as it was really hurting my hand.  After about 10 more minutes I was really wishing I had just cut the unit in half like so many others did but I was already in it so I pushed on.  After about a total of 30 minutes of prying I finally had the bezel off!

[Introduction Thread]

Hi everyone,

I am now a new owner of a 2000 V11 sport.  It is actually the bike which was recently sold by forum member Velofish.  I have to say that I have been lurking on here for about two weeks now and there is such a wealth of information here!  I want to send out a thank you right away to all of you for posting all of it, I have already leaned a ton and will continue to read through all the FAQs and How Tos.

Velofish did a great job of performing and documenting the regular maintenance so she runs great which allows me to enjoy riding while working on 'quality of life improvements.' 

My first order of business on this beautiful machine is getting her gauges working. Currently the Speedo has the classic wobble and the Tach is non-functional.  Thanks to all of the posts here I have already been able to narrow down the Speedo wobble to either the speedo drive gear at the transmission end or a bend in the cable.  I will confirm which by the weekend.

A little warning that you might see a couple of old threads resurrected as I search through all the great past discussions for similar issues to what I am dealing with and posting either more questions or confirming that I was able to resolve the issue following what others have already done!

I have already got my Guzzidiag and TPS cables on order for the Decent Tune Up and am building a spreadsheet of all the other little parts and pieces will need as I plan to execute the Tank Off Maintenance Checklist later this year.
