MOTOR METER RACING 85mm 12/24V Diesel Tachometer with Bulb Back Light

Just had to dial it in and it's somewhat accurate. It works though.

I brought this tacho thinking it would connect to my alternator. Others said it was easy to install. I cannot install it or find any detailed instructions on how to do it. The little piece of paper with a view diagrams that comes with it is hopeless and also I now find it may need a resistor installed between the alternator and the gauge or I could blow up the gauge or burn down the tractor. Very frustrating that makers of these products don’t at least provide easy to understand detailed instructions. Guess you get what you pay for.

This was the only tach I could find that went to 4k rpm and was compatible with a single cylinder motor. Needed this for lawn mower build. Looks cool and works great. Calibration is key.

Trabaja bien pero necesite un convertidor de voltaje a 5v deberían de decir que necesita 5v, tuve que averiguar a qué voltaje trabaja y el diagrama solo marca una resistencia pero no te da la información
