Check to make sure your cable didn't break. Happened to me a couple years ago.

Hi Mr. jdajani28,

Yes, it's usually just the cable but it could also be that the internals of the gauge itself needs cleaning. Try a new cable first.

anyone know how to keep the tach cable from breaking? i've replaced it twice and they both broke within weeks...

Make sure the cable gets well lubed before installing.

Welcome to GSR.

Where are you located?

A RPM guage is also called a tachometer, often called "tach" (sounds like "tack")

How to fix it:


First: Recognise that this would not be an electrical problem. The tach on GSes are mechanical. Are cable driven by a spining flexable thing in the tach cable.

Second: Find the cable and disconnnect from back of the tach.
Start engine and see if the thing is spinning. If it is, try holding it lightly with your fingers, if it stops then you know it is broke and the entire cable needs to be replaced. (cost maybe $15-20)

Third: Learn that the cable needs to be lubricated every so often or the tach will start jumping around and then cable break after awhile. Same with speedo cable.

Thank you for your valuable feedback, please let me know the proper way to lubricate the cable and what kind of a lubricant should I get. I am located in south east Michigan.

Do what Redman said......

Second: Find the cable and disconnnect from back of the tach.
Start engine and see if the thing is spinning. If it is, try holding it lightly with your fingers, if it stops then you know it is broke and the entire cable needs to be replaced. (cost maybe $15-20)

After his test,and holding disconnected cable vertically, I add a few drops of light oil and let it run down into cable.
