    Hi all - I'm looking at changing out the stock gauges and replacing with something smaller. The concern is that the replacement gauge only has one programmable general alarm / alert light.

    Am I stuck having to choose only one of the four (MGCT, MI, ABS, and General Alarm (RPM)) that are currently present on the v7iii?

    Is it possible to send the signal from all four to a single alert light on the new speedo?

    Thank you!

    My understanding, from previous thread, is that the tach on v7iii can not be easily replaced as it is integral to the ECU. I was hoping to do the same... but doesn’t sound practical.

    Quick test is to unplug the speedo (and tacho) on the back of the gauge, and try to start the bike. If it does, you can do whatever you'd like.

    Even if it did work, now that I know what all the tach does, I don't think I would replace it. Sounds like you would loose the ability to control the MGCT (+ trip meters, distance travelled in reserve, temperature, etc.) Little overkill, but kinda nice. Gauges on my previous bikes (Guzzi v11 Sport, et al) were pretty basic in comparison. What I wouldn't miss at all is the freakin x-mas tree that lights up when you start the bike — can they tone it down a bit please! Seriously...I really don't need to see the left/right blinker warnings flash endlessly. If you know any hackers that can turn that sh*t off, please let me know.

    Throw a sack over the gauges before you turn the key on.

    I very much doubt you could just parallel up all four alarms to one indicator, they are bound to conflict with each other somehow, so you would have to think of a way to keep all electrically seperated.
    Then of course you would have the fun of seeing an alarm warning and trying to work out what it was for, some are actually important.

    But it's your bike, your life. If you want to risk it because the ABS has failed and you hadn't realised, it's up to you.

    I like the light show, and prefer the informational displays over my older bikes' lack of information. Diff'rent strokes for different folks, I guess. I do wish I had the big white-faced tach that my LeMans V had, though: I thought it looked darn cool! :D

    In fact it should be fairly simple, simply set up an "OR" gate by including a small diode in series with each alarm source.

    But I agree that it wouldn't be the smartest thing to do.

    Thanks all. The guy I had lined up for this bailed due to the risk / his ability. Will need to continue to look for options...
    The original plan was to replace the dual gauges with the Motogadget Chronoclassic. Then I thought I could add 5 of these to handle all the other warnings from the bike. https://www.amazon.com/dp/B000THMK66/ref=cm_sw_r_em_apa_9pLPBb6KJ0NWP Figured these or just one light connected to multiple ECU alerts could be figured out and reset using the ECU re-flash tool when tripped.

    Going to see if I can get the box and cabling from this set up to compliment my Chronoclassic baakmotocyclettes.com/en/home/107-mini-speedometer-for-moto-guzzi-v7.html

    hopefully good news to come... thanks again.

    The flashing doesn't bother me much but what I couldn't stand was the blue high beam indicator. It's brighter than the headlight reflection! I put a little black sticker over it. It cut the brightness a bit.

    I do the same. I usually turn the instrument lighting to minimum, but it doesn't affect the indicator lights enough, and that high beam light is simply too bright.

    For those interested - the latest from BAAK. "there is no way to fit a Motogadget Chronoclassic on a V7 III, we’re currently trying to develop an electronic box that would enable us make such a modification but it’s not completed at the moment. The speedometers / wiring harness / electronic boxe parts we offer on our website are not compatible with the V7 III."

    The saga continues...
