ELING Universal Tachometer RPM REV Counter RPM with Hour Meter 3000RPM 85mm 9-32V with Backlight

Works like it should. Can be adjusted quite accurately.

I (we) worked real hard to make this tachometer work on my sailboat (YANMAR 3GM30) auxiliary diesel. This tach has a single wire pickup that should have connected easily to an alternator (if I had the right alternator, but this single wire pickup did not work with my two wire flywheel sensor/generator. Mechanic (on-line at "JUST ASK") suggested a new alternator or purchase the replacement proprietary YANMAR tachometer. As a 40 year old boat with many owners there is a lot of "jury-rigged" electrical work in that engine compartment. So I am still scratching my thinking machinery to find a solution. This tach is super to look at, fits perfectly in the cockpit cut-out, has a great back-light and engine hour meter and really WANTS to work...but just cannot connect in this situation. Pretty sure it is my engine problem and not with the tach. If anyone has suggestions, I am listening!A few days later...it works great with a jumper off the neg lead to the magnetic sensor on the flywheel. The tach needs to be set with the exact number of flywheel gear teeth as that is where the magnetic sensor is mounted. My Yanmar has 97 teeth on the flywheel (found in engine maintenance specs) so that is what I set and now life is all good. Will put in a switch for the backlight so I can scare myself out on the water at night with my engine RPM all aglow!

Looks great but unable to get it to read rpm from speed sensorReturn is likely to happen

Boat tachs

I bought this for a 1963 Case Tractor converted to an alternator. After installing as instructed, the unit would flicker when powered up but would not read the electrical pulses when the tractor was running. I returned this unit and bought a Bosch and had no issues. This obviously could have just been a bad unit but I didn't want to chance it.

this tach did not work out of the out of the box . I don't read other language well so I am at a loss. this is is street rod prodject so I didn't know I had 30 days for warenty y. don't buy this tach .

I installed this on a diesel John Deere backhoe to the alternator. It seems to read correctly at idle but when accelerating the engine, it only moves a tiny bit. Hours are counting. I know I wired it correctly because old tach worked. Tried several setting changes, same result. I've contacted Eling though their website. We'll see if they respond.Update:Eling has responded to my request for support. Although my issue isn't resolved yet, at least they have responded. I'll do another update as the support request progresses.

Nice display, I tried to hook it up to my coil and it doesn't read any rpm. I'm working with a 1956 tractor with points.
