TACH ISSUE

[izuizme]

I have a new (old) boat I just noticed that when I turn off the motor the tach needle does not stay at zero rather it drifts up to around 2k and stops there.Please advise a remedy.

That is normal.<br /><br />If it was to drift up to 2k when you turn the key to on...then its a problem.<br /><br />TMD

Re: TACH ISSUE

The tach is not spring loaded, it's more like a reostat, so when you turn the motor off, you are also killing power to the tach. Therefor it just stays basically where it was when you killed the power. <br /><br />It does not draw any power once you turn the key off.
