JPI slimline tacho

Recommended Posts

Hi Guys

 

Recently my slimline rpm gauge, after a period of being intermittent, stopped working altogether with the display just showing zeros (default) . I bought a replacement and have fitted the sensor, gauge and new wiring but still the rpm gauge is just showing zeros.

 

I'm at a loss to explain the problem, can anyone point me in the right direction?

You bought a complete replacement and it's still not working? Sounds like some sort of operator error. ;)

Does it work on your workbench, when it's not built in?

That tells me you have a problem with the sender line----or the sender itself

I assume that the power and ground line is ok since it at least reads zeros.

 

Eliminate the problem with the aircraft wiring by tapping directly into the sender with a separate line. If still zeros, then you may need to buy a new sender.

the new sensor was U/S replacement fitted and working

Sorry---did not understand the post---and I am interested to see what was wrong. Sensor? Wiring? Installation error?

the new sensor i bought from JPI was U/S on delivery, i returned it to them and the replacement is now fitted and working as normal.
