Tach readout gone weird

[Guest]

Hi All.
I have a 1989 GL1500.

Took bike out of garage yesterday , everything all ok.
Did a check of all fluids and undid the radiator cap. A small amount of water came out.
All appeared ok so put cap back on.

About an hour later I went to go out and started bike and noticed tach reading 1500rpm at idle, (norm is 800). :? :?

Under acceleration tach now goes into the red at anything over 1/4 throttle.

At all speeds from 30mph to 60mph in top gear tach now reads around 1000-1200rpm above norm. :?: :?:

All other gauges reading perfectly.

Have checked all connections and assertained correct voltage reading at tach.

Any help greatly appreciated.

I don't have a clue about the 1500's. You might want to do a search or ask the question at Steve's Site:

Hi fellas and thanks for your input.

I had also listed help on Steve Saunders site.

Pulled all the connectors apart and cleaned them with contact cleaner, cleaned up all the earth connections and problem solved
