sefner Posted November 15, 2008 Share #1 Posted November 15, 2008 My speedometer neddle is resting on bottom of the instrument panel. Been this way since I bought the bike. I thought I would open up the instrument panel and see if i can re-attach the needle. I have the instrument panel out of the bike (using the great instructions found on this site). I've removed the 6 pan-head screws located along edge of the back panel. The illumination knob seems to be preventing a complete speration however. There doesn't appear to be an obvious way of removing the knob externally. Am I missing something (probably)? Any help help or suggestions greatly appreciated. Thanks, Vince 84' Venture Link to comment Share on other sites More sharing options...
sefner Posted November 15, 2008 Author Share #2 Posted November 15, 2008 Nevermind. :-) Duh! There's a set screw inside the knob. "That's what that little hole is for..." - Vince Link to comment Share on other sites More sharing options...
Yammer Dan Posted November 15, 2008 Share #3 Posted November 15, 2008 Let us know how this come out. I thought once the needle fell off it was junk. Someone didn't lube it in time. Keep us posted. Link to comment Share on other sites More sharing options...
MiCarl Posted November 16, 2008 Share #4 Posted November 16, 2008 Other trick is getting the computer module out. As you're looking at it from the rear there is a light pipe that goes to the right. You need to lift the left side up, then move it left as you rotate it out of it's hole. Link to comment Share on other sites More sharing options...
sefner Posted November 16, 2008 Author Share #5 Posted November 16, 2008 The odometer is still working. Not sure if that indicates the rest of the speedo is also working. I bought some "Kable-Ease" cable lubricant from the local auto parts store. I'm in the process of putting every thing back together right now. I'll update my results.

Ivan Posted November 16, 2008 Share #6 Posted November 16, 2008 I attempted to do the same thing today, but couldn't get the little screw out. That was my first thought. Is it a crosshead or a hex head? I imagine mine is backed with 24 years of gunk. Link to comment Share on other sites More sharing options...

sefner Posted November 16, 2008 Author Share #8 Posted November 16, 2008 No go. Lubed my cable, hooked everything back up. Odometer still works, but no speedo. Also, the left side of my dash is almost completely in the dark. May have been that way before I took the instrument panel out for the speedo. Tonight was the first time I've rode the bike at night since I got it. Very warm here in N. Calif for this time of year. 66F at 7pm. Perfect for riding. I had a smile on my face even though my speedo still isn't working. Should I give up on this speedometer? Is there any way to get inside it and fix something? Maybe I'll head to the local junkyard and look for gen 1 Ventures. Worth a try I suppose. Link to comment Share on other sites More sharing options...
MiCarl Posted November 16, 2008 Share #9 Posted November 16, 2008 Next time you're in there replace the bulbs, should take care of the dark problem. Link to comment Share on other sites More sharing options...
Neil86 Posted November 16, 2008 Share #10 Posted November 16, 2008 (edited) The speedometer needle has no direct mechanical connection to the odometer. The cable drives a worm gear to drive the odometer, and spins a magnet that sits inside a "bowl" to which the speedometer needle is attached......so its magnetic force that causes the needle to move, with a spring on the needle to bring it back down to zero. Ensure nothing is interfering with the needle movement.....you can rotate the "bowl" and should see the needle react. Once you have freed it up, if you rotate the cable CCW where it enters the speedometer housing you can check operation prior to reinstalling the dash.

Bill W. Posted November 24, 2008 Share #11 Posted November 24, 2008 When you're putting the top cover back on, be sure and make sure the needle for the volt meter is above the stop. If you don't the needle can't move UP when you turn on the ignition! I spend a good part of one day troubleshooting my charging system before realizing this little fact! Doh!!!!

That one seems willing to move backwards on the wrong side. I have a buddy that has one like that. Link to comment Share on other sites More sharing options...
sefner Posted November 29, 2008 Author Share #13 Posted November 29, 2008 Looks like the old speedo is shot. Lot's of metal shavings and it appears that part of the bracket that holds the "bowl" is broken. Not sure if anything can be done to salvage it. Good news however. I bought a complete instrument panel off ebay for an 83' I swapped the speedo and the tach from the 83' (much better condition than my 84'). Works like a charm. Today I realized that I've been riding a little faster than I thought. :-) Link to comment Share on other sites More sharing options...
