Product Introduction
How to install it?
- Cut an 85mm (3 3/8") hole in the panel and allow a clearance of 70mm (2 3/4”) behind the panel to fit the gauge.
- Put the gauge in the hole.
- Using M4 nut and C type bracket to seal up the gauge.
How to connect wires?
Red wire --- Power Positive.
Black wire --- RPM Signal.
Orange wire (backlight) --- Power Positive.
Blue wire --- Power Negative.
Please note: Tachometer can be connected to 12VDC and 24VDC power directly.
Why Don't get RPM signal?
Tachometer sometimes cannot get signal by ignition system. So, I suggest Tacho sensor signal. It is more stable.
I suggest you can buy a Tacho sensor from Eling Parts. ASIN NO. is B07RR8NQ45, B07RN3HJ72.
How to be setting Tach RPM Ratio?
1. Turn on the power supply first.
2. Press and hold the mode button for 3 seconds to enter the setting speed ratio mode. then adjust speed ratio from 1-300 according to your request.
3. After setting, Data is automatically saved.
4. Please note: If your sensor is installed on the flying wheel panel, the RPM ratio is equal to the number of gears of the engine; If the speed signal takes from W-Terminal, the RPM ratio is equal to the half of the number of poles.
5. Normally, When the engine at idle state, tachometer shows 600-800rpm that means speed ratio is correct. If not, you can turn down or turn up speed ratio to check RPM difference.
Package Includes:
1x Tachometer
1x Multi-plug socket

È montato sulla mia barca con motore Volvo D2 collegato tramite cavo su w dell'alternatore e funziona egregiamente.Facile da collegare, bello esteticamente, waterproof (almeno oer ora) e già dotato di bottone per la calibrazione dei giri.Un affare se paragonato ai suo cugini che costano da 250 a 700 euro ...

Build quality is okay, and the wiring was the same as the tach that I already had, but it did not work with my single-cylinder application.

Fits perfectly and looks great, it’s on the boat so I can’t start it up until spring but so far so good. I powered it on, back lighting works, the tachometer was showing about 400 RPM but the needle immediately dropped to the zero when the power went on. So far so good I’ll update in the spring if there’s any change. —- Just started up the boat and the tack is all over the place, one moment it’s reading 1000 RPM the next one 3000 RPM and two or three seconds later 2000 RPM. no stability whatsoever. More junk.

I had a hard time getting it to work. Instructions are useless. I have a simple v-8 motor. No support. I removed it and installed a Bosch.

Worked right away after install. Haven’t had time to sync exactly with engine so can’t say on accuracy. Weak point: engine hours hard to see in daylight.

I made a new panel for my sailboat's-3hm35f yanmar diesel. To make the tachometer work properly, I connected one of the 2 wires from the magnetic engine flywheel sensor to the panel ground wire and the other flywheel sensor wire to the tachometer sensor input wire. All is good.

Just press and hold the black button on back bump the rpm'S to go down (-) or hold and bump up (+) the RPM's . Probably too technical for the layperson ... they should hire a mechanic to install. Pftttt

I bought 2 tachs to replace my flybridge units. I have twin 454 Crusader inboards that drive the signal off the coil.The instructions show a tach sensor and an alternator. There is no information except for speed ratio. The 8 cyl shows to set it at 4.0. All good but no reading at all. I took my professional tach/ dwell meter and checked the output signal wire at the dash and it works great. So the Eling tach is not reading the signal. So now I have two useless tachs. IF ANYONE HAS INFORMATION ON HOW TO MAKE THEM WORK I AM ALL EARS!. I was a certified marine mechanic and I am stumped. Someone posted tap the ground wire? does not make sense... I do not want to short out my other tach on the main station panel.
