Tachometer starting to show its age?

[rlucas]

Do we have a head count?

Headcount looks like four:  You, Paul, Mike (although I haven't heard from him in two days) and me.  I heard that any more than three FJ's is a rally...so I'm still callin' it the RR 2014!

Hey, it's an FJ Rally. It's all about the people there, not how many.

Hi guys, not to hijcak the thread, but I have a simular issue with my tachometer...

Its starts "jumping" between 5000 rpm and 5500 rpm and wont become steady until i pass 6000 rpm and enter the Kookaloo zone... (which now how to visit frequently!) 

No indication of in other areas, all though if i twist the throttle to full open straight away, it sometimes shows less rpm when I can hear the enigne is hitting the redline and it shows 500 to 1000 rpms underneath, and if i keep the throttle stead or change gear it goes back to normal and correct behavior...

Any thought? Bad wire connections on the coil?

Cheers
Ken
