My Speedo and Tach are not working on my new to me '78 CX500 and figuring I would eliminate the possiblity of it being cable related I bought new Tach and Speedo cables.



Well, I replaced the Speedo cable and it had no effect. Could I have possibly done something wrong on install?

I tried to make sure the cable end was engaged when I attached it at the speedo and I ensured the blade was in the slot for the speedo drive at the front wheel.



I immediately saw one cause for the Tach being non-functional...

I found that the Tach didn't have a cable and the PO told me the tach had problems...so I figured it would need replaced.

It might be OK and the lack of a cable may be it's problem.

We'll see this weekend when I get a chance to work on it.



If I need a new Speedo, then what years work for the '78 CX500? I'm presuming the GL500 isn't compatible and that at least '78 and '79 CX500 speedo and tachs are compatible.





Thanks!

Achille, Lucky, and marshallf3,



Thanks for the tips and info.

I'm better armed to diagnose and hopefully solve the mystery.

USA Ebay only has a tach for the '78 but I have a spare tach. I'll check the UK ebay website and set a search for '78 CX500 speedometer there...



Thanks!

Some of the clocks (speedo and tachs) in the console face are from '79.

So, is the '78 a one year only deal? If so, why?



Thanks!

Sorry, too little sleep and I was using the british speak for instruments/gauges...

that really wasn't clear.

The '78 has the fairing in the US. I'm not sure if the '79 did or not. The bikes I'm seeing for sale on the UK ebay site have the same face and console/instrument panel outline for the '78 and '79; as if they both have the bikini fairing (maggot).
