tachometer bouncing all over low range

Took my Defender to have an engine noise looked at which my mechanic couldn't locate the problem but removed valve covers and intake plenum and put it back together. The tapping still occurs but drives normally.

I get it back but the tachometer stopped working correctly. It is now very bouncy and indicates almost always in the very low range (0-1 K) irrespective of how hard I am pushing the gas. The only time it is somewhat accurate is when it is out of gear in idle but the needle still bounces more than right before I had work done on it.

I'm getting a little frustrated. Is there anything I should look at inside the engine compartment myself that would be a simple adjustment as I'd rather not have him work on it again.

Check to see that it's fully plugged into the back of the alternator.

Yup- or maybe your alternator is on its way out... More likely the connection since you just had work done.

Thanks guys. I usually don't work on cars; just started oil and filter changes with the acquisition of the Defender. I fix hearts (put stents in arteries) not cars.

Can anyone take a cell phone pic of the alternator and where the plug for the tach should be so I can check it.

Thanks Jay and all. I just pushed it in and all is well.

I looked on the RN site and an OEM LR alternator is close to $800 while a Proline is about $300.

Now, I just need to find a local mechanic who is more detail oriented and who knows older LR well.
