Hi,
Can anyone help.I have tried 2 rev counters on my bike(1989 KR1) and neither works.Battery is charged,bike starts,all lights work.Any way i can test these counters,i don't think both are knackered.Any other tests i can make.Thanks.

Hi,
Have tried 2 rev counters and 2 cdi units,still the same.The lights on the rev counter work fine with both cdi units.

Had a look and couldn't see any wires broken.I have checked the brown wire at the rev counter,it has 12v.Tested the blk wire at the rev counter with bike running,getiing voltage up/down so i don't think it's the cdi.Will try another rev counter.

Thats interesting , I have disconnected the lights and indicators and the tacho seems to work fine

Could be different wiring for OZ maybe but have seem nothing in the manual .

I was told by a mate years ago that they can get flip up if they are left face down for a period of time.
Since then I have always stored gauges carefully and never had a problem when I have come to use them
Or maybe it was just a dream I had
I must start putting more tobacco in
