Hot system? More like Hotmess!

Tasks seem to alternate between reading an O2 signal and who knows what? It is clear that it will show voltage when the car is cold (and the sensor hasn't reached temperature yet) but since it never converts ONLY O2 READING it is useless as a sensor. This behavior makes it impossible to keep track of exactly what the machine is doing in open and closed loop and when it is switching between the two modes. Pure garbage!

Better than expected

Better than I expected. The display is bright and easy to read, and the blue color looks very nice. Seems to work fine, I use it on a UTV to monitor voltage at a glance so I know when it needs a charge. The only thing I don't like about it is the connection to the sensors, it's a pre-wired connector which makes installation easier, but if that little connector breaks or the cable is pulled the wrong way it becomes a problem. . I would prefer to see the terminal mounted on the back of the…

I assume there are two versions of this voltmeter. .

I assume there are two versions of this voltmeter. One has two wires and the other comes with a three wire harness. I have a 3 wire device. I bought it to replace the sand rail ammeter. At first it didn't work at all. In preparation for testing on an electronic desktop, I noticed that the connector housing on the unit was not set far enough for the pins to protrude to make contact with the harness connector. This was corrected by applying gentle but firm pressure to the case (on the unit) so…

Automotive Voltmeters - Gauges

Basically I bought this gauge to fill an empty spot in my gauge block until I needed a more expensive functional gauge for my car so I wasn't expecting too much from this gauge . Reviews and price but today I got my volt meter and tested it at home on my AC voltage source and I found this. It is accurate to within tenths of a volt compared to a high-end meter. If the voltage falls below 11.5 volts, the signal lamp lights up. I definitely like the blue color. I will also say that I have compared
