Modern tacho alternator driven

No eBay APP ID and/or Cert ID defined in Kunena configurationWould you not need an adjustment on the tacho to cater for different pulleys on different engines? A jump wire added to an ordinary alternator to give you the "R" output will probably be a fixed (and most likely wrong) signal. I know I had to get an adjustable one for my Perkins Commer. I had to lay under the truck with a laser tacho tracking a white line drawn on the crank pulley while my mate screwed the adjuster on the back of the tacho to match with the correct speed.

In setup mode , the tacho has a 10-300 adjustable setting so there is a little bit of guessing on my part , I couldn’t get into the setupMode,because there was no signal I know the 2 rubber plugs are for adjust it and change background light , I’m currently studying Chinese so I can read the instructions !
