RPM sender unit

[Hayloft]

Hi there,
Anybody replaced the RPM sender ?
When first startup my 3520H sticks on really low RPM no matter what throttle is set at. After several minutes, like during warmup, the RPM starts reading normal.
Hmmmm I figured it's likely a sender unit starting to go.
2014 3520H model.

The tachometer on the dashboard gets the signal from the alternator. It's a single wire that comes out the back.

You may want to check if the plug is fully seated and without corrosion.

Forgot to add on the other post but if that doesn't work, try wiggling the plugs behind the dashboard.

Might be necessary to pull some covers out though.
