Quick Specs

DESCRIPTION:

This compact and easy to install module will allow you to easily adapt AutoMeter tachometers and shift lights and many other aftermarket RPM-based devices on your alternator-equipped diesel or non-standard ignition gasoline engine. Equipped with a sensor which is mounted to the alternator casing, a one time setup calibration is accomplished via push button interface on the module to synchronize the alternator signal with engine crank RPM. Perfect for diesel performance applications looking to add a tachometer or upgrade from factory equipment and a great problem solver for engine swap builds in need of working instruments. Pair it with AutoMeter's low-rev tachometer models to complete your diesel-specific gauge installation.

Rated 4 out of 5 by from Sensor works fine, easy to install. Had to use a 1K pull up resistor for the adapter to work with a VDO tachometer gauge. A circuit diagram of the adapter o/p circuitry would have been helpful.

Will this work the dual diesel alternator setup?

Asked by: Ericjo

Do you have to use one of your tachometers with this or can I use a different brand along with it.

Asked by: Anonymous
Thank you for contacting us. We can only guarantee functionality and provide if you use an AutoMeter tachometer. The 9112 creates a 0-12V square wave which should technically function with other aftermarket tachometers designed for standard/electronic ignitions.

Will this diesel adapter work with AutoMeter Mini Tach part 2306? Thanks.

Asked by: MeteredAir
Thank you for contacting us. If you don’t own a tach yet, we’d actually recommend 2888 which is a small diesel tachometer and no separate adapter is required. However, the 9112 creates a standard tach signal, so it is compatible with the 2306.

Does this output a signal that can be used by a dynamometer? I have an all mechanical diesel with no crank signal.

Asked by: The Driveway Engineer
Thank you for contacting us. The 9112 uses a pick-up that is specifically designed to mount to an alternator. That “raw” signal from the pick-up is then converted to a traditional 12V square wave tachometer signal within the module itself.

Will this adapter still output a correct RPM when my battery is fully charged and the regulator has turned off all field current to the alternator?

Asked by: Mrcandy
Yes it will.

Hi. I've got a classic SMITH'S petrol/gas tachometer on my diesel Land Rover Defender. Will this device allow me to somehow get a reading from my diesel engine to my petrol/gas tachometer? Also, do you have a similar arrangement for a petrol/gas speedo?

Asked by: Musa
Hi, This adapter creates a standard tach signal: 12 volt square wave at 4 pulses per revolution. We don't have data as to what type of signal your Smiths tach requires, however. Thanks, Jim

Jim, I believe you misunderstood my question. Will this adapter work on a neese lavel alternator? My alternator has a large hot and ground and only one other wire that goes to the ammeter on the dashboard.

Asked by: Lenny still lost
Yes it will. I have a 1988 Ford E-350 with 7.3 diesel and it works perfectly.
