2003 VN750 speedometer failure

Last night coming home a jangling noise from the handlebar/gauge area -- thought my keychain was hitting the bars but the noise only stopped when I grabbed the speedo housing. Needle was steady but the speedo gauge seemed to be vibrating. Then I looked down and -- needle stuck on zero. Now when I am moving there is a faint whirring noise coming from the gauge area.

Pretty sure the speedo is DOA.

My question -- there does not appear to be a speedo cable. Are these completely electronic? should I just bag it and order another speedo? If so, the odometer on the replacement won't read right. How does one document this change -- if I ever sell the bike I have to represent what the mileage is...

Any recommendations on replacement speedos?

There is supposed to be a speedo cable. The tach is electronic, but the speedo is run off a cable that goes from the left side of the front wheels hub to the bottom of the speedometer gauge.

If you do not have one, that would explain why it ain't working.

The speedo's are 100% mechanical. If there is no cable conencted to it, you found your problem. The cable are prone to break right where they make the turn to head up to the speedo from the wheel sender.

Local Kaw dealer ~ $ 20.

If you are missing the outer cable tube, you'll need one of those too. The inner cable is what usually breaks, and its easy to replace and cheap for 20 bucks. They have to be kept oiled too or they will break...

mine stopped working- turned out that the inner speedo cable had snapped. 5 minute fix and $15..
Also, during a ride, the whole attachment on the vibrated off the speedo housing and was trailing on the pavement at 50 mph.. I stopped, put it back on, and took off... lucky for me I noticed it immediately... otherwise it could have been bad :-P

Boy you guys had it pegged. I got out there in daylight and lo and behold, there was my speedo cable hanging down. The outer housing detached from the speedometer gauge. The loop holder caught it and the stiffness of the housing prevented it from sagging down and dragging on the pavement. Lucky me.

The inner core was intact so I just lubed it up with the Honda lube advocated for splines on these bikes, and screwed everything back together. Good as new.......

Of course that was when I also discovered that the tach housing had detached from the rest of the tach instrument -- turns out the plastic pedestal the housing screws to had broken off inside. I never saw it because it's behind the windshield. That necessitated removal of the headlight to get at the back of the gauge mounting brackets so I could JB-weld the plastic back together and reassemble the tach.

After waiting an hour for the adhesive to cure I went out and rode the bike at 70 mph for a half an hour. Gleeful.

Mine did the same thing, only I was dragging it for about 10 miles. I pulled over and after some required cussing, managed to get it reattached. It was only scratched up on the connector. Cable was fine. Tightened it up when I got home.
