Hi, all.
I've been dealing with a dead speedo on my first K-bike (91 K75, ex-RT), going through all the posts both here and at our very helpful neighbors down street on the internet, the K-100 forum. Did all the continuity, sensor checks (280 ohms static, and puts out voltage at speed), and much else and all checked out right up to the 3 pins at the top of the back of the speedo, which I cleaned, roughened a bit, and reinserted with a very thin coating of copper antisieze. Even checked the opened cluster with the plug inserted--all good. Continuity everywhere. But, dead speedo.----
The Karamba program was great, along some solid tutorial help from Robmack. This is a great program, and a few reports both here and down the street that it's complicated aren't all that accurate. It's pretty well a walk in the park, and told me that my odometer was working and bang on, but the speedo was dead. Robmack suggested the servo motor might be the problem. So, I took the speedo apart.---
I'm now looking at the attached pics. Anyone been inside the speedo, I mean other than the odo-wheel repair? Does it make any sense to check for anything? I see a coil, a board, etc. Is this a dead end, and I'm in for a new cluster? Or should I press on and undo the 3 bolts on the back and go "deep speedo"?---
Best, Tony
