installing this model (233904) shift light tacho into my mid 80s rx7 that has the 13brew engine swap running the Haltech Sprint RE ecu.. do I have to snip the wires? what setting? I dont see any, does the cover come off the tach?Thank you for your question. While we do not know all the details of your specific application, the 80s RX7 was a 4 cylinder two pulse, so you would cut the brown and orange wires on your tach to calibrate it appropriately.Date published: 2019-02-26
Would like to know if I can get the wiring diagram for this tach. I purchased it from a guy at work but he had no information to go with it.Thank you for your question. Here is a link to the Operating and Installation instructions: https://www.autometer.com/media/manual/2650-1077.pdfDate published: 2019-01-10
Does this tach require a 5V input signal? i am wanting to use it with a standalone EFI system and that is the only signal the CPU provides as an outputThank you for the question. The 233904, along with basically all of our tachometers, requires 12V for power and the signal is a 0-12V square wave. Often, they will trigger down to a 5V square wave, sometimes a "pull up" resistor may be required on a 5V signal.Date published: 2019-01-03
Is this 233904 just a shift light or a tachometer plus the shift light Thank you for your question. 233904 is a tachometer that comes with a shift light.Date published: 2019-01-03
Does the rpm gauges have issues if connected to a 16-18 volts battery istead of 12 volts?Thank you for your question. This gauge will work on both 12v and 16v systems.Date published: 2019-02-26
is Chinese? or American?Hi Manu, thank you so much for contacting us. This Auto Gage tach is designed, engineered, assembled, calibrated, and tested in the US using components sourced from China. The AutoMeter line are the American made units. Here is a link to the AutoMeter equivalent tach: https://www.autometer.com/5-tach-10-000-rpm-shift-lite-sport-comp.html Hope this helps!Date published: 2018-07-24
I have an auto gauge tachometer by autometer that will not Return to Zero is this repairable or am I missing something about adjusting it, also if there is a repair facility could you give me a phone number or address or someone to talk to thank youHi David, thank you for connecting with us. This may require some additional troubleshooting with our Technical Support Team. Some models never actually read zero, since they go into shift-set mode with 12V supplied and will begin reading RPM once a signal is supplied.

I have had this tach for about 3 months installed on my truck. It skips and jumps right at 2300 and 3600.
