Single engine Yanmar 6LPA STP. Tachometer seems to operate OK at first (though the readings are suspect -- seems to read higher RPM than I would expect at a given speed). But after a while it just kind of... fades out and dies.
I suspect (hope) that it's just some connection that needs to be cleaned or tightened. Can anyone direct me to the exact location of the tach sensor on this engine and describe what it looks like. I have the service manual, but it's not very helpful.
Also, if it's not the connection at the sensor or at the instrument panel, where else should I look? Could it be a weak battery? The two batteries are 4-5 years old, well within their 84 month warranty, and appear to be holding a charge OK. But, the purchase surveyor noted that I should probably replace them due to their age.
Thanks.
